Gravitational potential energy Gravitational potential energy (GPE), is the energy of position or place. When learning about GPE we need to learn the formula and understand the concept. The whole general concept of energy is energy cannot be created nor be destroyed. Gravitational potential energy is energy an object possesses because of its position in a gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be at
the same time delivers a lot of thrill to the rider. I am going to explore the sense of ‘weightlessness’ during freefall, and how ‘forces’ are used to ensure that the ride is not dangerous, I will also mention how gravitational potential energy converts to kinetic energy as the ride drops. Physics principles ================== Weightlessness Freefall is a term used to describe how an object is moving through the air when there are practically no forces other than gravity acting
Hypothesis The greater an object's gravitational potential energy the longer it will take to cease all movement. This is because it will have more kinetic energy - and if we assume that the energy is removed at a constant rate by friction then the more kinetic energy an object has the longer it will continue moving Background knowledge This experiment will be looking at the transfer of energy from gravitational potential energy (gpe) to kinetic energy (ke) and the effect of friction on
ramp the more gravitational potential energy is stored. The reason is the Gravitational potential energy is the energy stored in an object as the result of its vertical position in this case it’s the height of the ramp. The energy is stored as the result of the gravitational attraction of the Earth for the object. In this experiment I am trying to find out the relationship of the height and the change in speed; which is a direct relation between gravitational potential energy and the height
is gravitational potential energy. GPE is the energy stored in an object because of its height. The energy is stored as a result of the gravitational pull of the earth for the object. GPE is also affected by the mass of the object but I am going to use the same trolley. I am going to increase the gradient of the ramp and therefore increase the height of the trolley. The higher the trolley is on the ramp, the more GPE it should have and this energy will be transferred to kinetic energy when
Measuring the Moment of Inertia of a Flywheel Objective ========= Measure the angular velocity of a flywheel and use conservation of energy to calculate its moment of inertia. Apparatus ========= Flywheel String Slotted mass on hanger Stop-watch Vernier caliper Metre ruler Theory ====== The rotational kinetic energy can be defined by the equation K=1/2 I ω2. Where I is the moment of inertia of the body about the axis of rotation. In this experiment
higher as well. This would mean that at higher points the trolley would have more gravitational potential energy. This would be a good variable to investigate because we can use various gradients but it might be slightly difficult to measure some angles with the protractor. * Height of start position- this affects the motion of the trolley because as the height gets larger the trolley gains more gravitational energy. This would be a good variable to investigate because there are many heights
displacement. The gravitational potential energy the ball has before it is dropped is converted into kinetic energy while the ball is falling and then into elastic potential energy as the force from the ground does work on the ball. But because the material the ball is made of is not perfectly elastic, friction converts some of the energy into thermal energy. The elastic potential energy stored in the ball when it has lost all its kinetic energy is converted back into kinetic and gravitational potential
certain height How a Tennis Ball Bounces As the ball is elevated the ball gains gravitational potential energy equal to the ball's weight multiplied by its change in height1. When the ball is dropped, the height decreases, and therefore so does the gravitational potential energy. At the same time, the velocity of the ball increases due to gravity, and therefore the kinetic energy increases, as kinetic energy half the mass of the object (in this case the falling ball) multiplied by velocity
and distance the ball rolls because the higher the ramp, the more gravitational potential energy the ball has, which is then transferred to kinetic energy. The length of the ramp affects the gradient, which affects the speed and distance the ball rolls. The surface of the ramp and marble cause friction, which affects the speed and distance the ball rolls. The weight and size of the marble affect the gravitational potential energy and the amount of friction, which affects the speed and distance the
KE at the bottom. As the car (marble) rolls down the slope, GPE changes into KE. Text Box: KE = ½ MV2 GPE = MGH As an object falls, its Gravitational Potential Energy is turned into Kinetic Energy. The increase in GPE is equal to the increase in KE. As energy is neither destroyed nor created, it must be equal (where there are no other energy transfers). From this, I can conclude the following: Text Box: ½ MV2 = MGH Since "m" is present on both sides of the equation, we can cancel
ball's bounce. However, below this height, where the kinetic energy carried into impact will vary between different drop heights, I believe the bounce height will also vary. As an object on Earth is dropped and bounces, the energy of that object will undergo a series of transfers. It begins with gravitational potential energy which is continually transferred to kinetic energy as it accelerates towards the ground. Some energy is lost in the ball's flight downwards and upwards due to air
swing from position A, through positions B and C and back to A again. It is the movement from 1 peak to another, i.e. one oscillation. I need to examine the factors affecting how long it takes for 1 oscillation to take place, In relation to the energy transfers involved. After I have done this I can decide which factor to use as a variable and which factors that I should keep the same. Factors affecting the time period of a pendulum Length of String: The Length of the string will affect
Physics of a Mountain Bike This paper will discuss some of the physics involved in bicycles. Specifically, mountain bikes with suspension. A bicycle is a very energy efficient vehicle. Its wheels allow its rider to make full use of inertia and gravitational potential energy. The basic design of a bicycle has been around for over 100 years and compared to other things, has changed very little. Some of the topics that will be covered are: frames, wheels, suspension forks, suspension frames, brakes
Conservation of Energy Physics Essay: The Conservation of Energy Since the beginning of time, energy has pervaded our earth. These days we rely on it to advance in our technological developments. We also need energy for a variety of other things such as: to keep our bodies alive and healthy, to run our machines and other technical devices, we also rely on energy to keep warm in winter and cool in summer. Energy is the ability to do work. People and other things can run out of energy (e.g. a marathon
related to the conservation of energy and will be investigated through a trolley going down a ramp. A simple trolley will be used to represent the vehicle and weights attached to the rear of the trolley via a pulley system will act as the brakes. Throughout the experiment energy will be transferred into many forms but no energy will be lost or gained. As the trolley is raised it gains potential energy, when released down the ramp this energy is converted to kinetic energy. When the trolley hits the
because when you drop the squash ball from a greater height there is more Gravitational Potential Energy, which will be converted to make the ball bounce higher. When the ball is dropped from a greater height, it will bounce higher. When dropped from 1m, for example, it has maximum Gravitational Potential Energy (GPE). This energy then converts to kinetic when falling, and when it hits the floor, some more energy is lost through
might cause the pendulum to move in a different way. With a little pendulum bobble there is very small air resistance. This can easily be observed because it takes an extended time for the pendulum to stop swinging, so only a small amount of energy is lost on each swing. Gravity The pendulum is motivated by the force of gravity acting on it. The more gravity the shorter time it will take for a complete swing. The less gravity the longer it would take for a complete swing Size
with a mass of 25 oz. (0.7 kg) and a diameter of 9.39”. Dribbling If the basketball was simply dropped from a height of 1 meter with no initial push from the dribbler and rebounded from the floor in a perfectly elastic collision, Mechanical Energy for the system would be conserved (1). However, the collision is not completely elastic and the dribbler pushes the ball with an initial force to ensure that it returns to his hand. To simplify the process I will first consider a situation in which
aerodynamics and Bernoulli’s principle. It explains the relationship between the velocity of a fluid and the pressure that the fluid exerts. A fluid gains energy when it speeds up as, for example when it goes through a constricting area in a pipe or passes around an airfoil. Since the gravitational potential energy is constant, the change is in kinetic energy. Since there is an acceleration of the fluid, the press... ... middle of paper ... ...d San Francisco.
