Title: The Effects of Height, Length, Surface, Weight, Size, and Material on the Distance a Ball Rolls Down a Ramp
Aim: The aim of this experiment is to investigate the factors that affect the distance a ball rolls when released from the top of a ramp.
Variables: The independent variables in this experiment are the height of the ramp, the length of the ramp, the surface of the ramp, the weight of the marble, the size of the marble, and the surface of the marble. The dependent variable is the distance the ball rolls. The controlled variables are the starting position of the ball, the angle of the ramp, and the surface of the floor.
Units: The height of the ball from the ground, the height of the ramp, and the distance the ball rolls will be measured in centimeters (cm).
Explanation: The height of the ramp affects the speed 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 ball rolls. The surface of the marble affects the amount of friction, which affects the speed and distance the ball rolls. The surface of the floor also affects the amount of friction, which affects the speed and distance the ball rolls.
I decided to use one type of ball, so the weight was constant. And the
Acceleration and velocity are mostly dependent on the number of dogs, the quality of the dogs, and how well the dogs have been trained, but it also can depend on friction and inertia. The lager mass an object has the the more weight it has and the more inertia it has.
In this experiment we positioned a marble ball on a wooden roller coaster positioned on a physics stand in the sixth hole. Throughout the experiment, we used an electronic timer to record the time of the marble where it passed through the light beam of its clamp. We positioned the clamp at a certain point on the roller coaster and measured the distance from the marble to the clamp; the height of the clamp; and finally the time the ball traveled through the clamp. After we recorded these different figures we calculated the speed of the marble from the given distance traveled and the time. We repeated the step 14 times, then proceeded to graph the speed and the height. Next, we took the measurements of position of the clamp, height, and speed and calculated the potential energy, the kinetic energy, and the total energy. Total energy calculated as mentioned before. Potential energy is taking the mass (m) which is 28.1g times gravity (g) which is 9.8 m/s2 times the height. Kinetic energy is one-half times the mass (m) times velocity (v2). Finally we graphed the calculated kinetic, potential, and total energies of this experiment.
As I was doing research on this assignment I came across a web page about the effects of gravity on mars as it specifically relates to the projectile path of a curve ball. I know that you cannot believe everything you read, especially when it comes to internet content, but the issue is still worth noting. I will mention this effect when the topic of spin on the ball is discussed. Gravity was the other force that was mentioned by the scientists. This isn’t too particularly exciting, because it’s always in
Gravity is the force that attracts a roller coaster to the Earth and determines how far along the track it was pulled. When a roller coaster crests a hill, the gravity takes over and pulls it along the track at a “constant rate of 9.8 meters per second squared”(1) according to the website Wonderopolis’ article titled “How Do Roller Coasters Work?”. This numerical value, (or concept), is called the acceleration of gravity. It means that no matter the shape, size or mass of an object on Earth, gravity will pull it down at a rate of 9.8 meters every second, assuming there are no other interfering factors to mess with the decimal. In the article “How does Gravity work?” Tom Harris describes gravity and height’s relationship by stating, “As the coaster gets higher in the air, gravity can pull it down a greater distance” (1). This means that if a roller coaster were on top of a hill one thousand feet high, it would be pulled a lot further along the track by gravity than a coaster on a hill with a crest one hundred feet. Why? Because the coaster at one thousand feet has a stronger pull towards the Earth and can go farther because of it. The aspects of gravity, the acceleration of gravity and its relationship with height, are all important aspects of the force gravity. In conclusion, gravity is a vital, while fascinating, type of phenomena to observe in roller
As a simple case, consider the simulation of document . In the frictionless case, the only force acting on the skater is gravity. Therefore, according to the conservation of energy, the sum of the kinetic and the potential energy remains constant. As the skater climbs the ramp, his height increases. According to document , as the skater’s potential energy is proportional to his height, the skater’s potential energy increases. However, the skater’s velocity also decreases as he climbs the ramp. Again, according to document , as the skater’s kinetic energy is proportional to his velocity squared, the skater’s kinetic energy decreases. The interplay between these two energies is such that their sum remains constant and the law of conservation of energy remains

Investigating the Bounce of a Squash Ball This investigation is associated with the bounce of a squash ball. I will be investigating 4 different types of squash balls, which have different, bounce properties and compare them to each other and relate them to why each different type of squash ball is used. The relationship will be associated with how different balls are used at different levels of proficiency in the game of squash i.e. the squash balls that don't bounce much will probably used at a less proficient level whereas the balls with the most bounce will be used at professional level. The different coloured squash balls I will be using are; white, yellow, red and blue, and I will be finding out what the difference is between them.

To investigate the affect the material of a ball has on the bounce height of that ball where the drop height (gravitational potential energy), temperature, location, ball, and air pressure of the ball are kept constant.
We ran into Newtons First Law, which claims that an object resists change in motion, as the marble rolled down the floor it didn’t stop until it was acted against by friction. As we moved on, Newtons Second Law came into play when we were creating our lever as we need a ball that would roll down with enough acceleration that it could knock down the objects. Newton’s second law claims, that F=MA. So, we choose a golf ball since it would have more mass than a rubber ball, but it would have less acceleration when the lever was started. This way, it would knock the upcoming objects. Newtons Third Law claims that every action yields an equal and opposite reaction. This is proven in our Rube Goldberg Machine when the small car was rolling down the tracks as the wheels pushes against the track making the track move backwards. The track provides an equal and opposite direction by pushing the wheels forward.
Dependent Variable ------------------ Rate at which the bubbles of oxygen rise, which will be calculated by observing how many bubbles of oxygen rise to the surface of a measuring cylinder (by means of downward displacement) in one minute. This will be measured in bubbles per ten seconds. Control variables: ¨ Volume of substrate used: 100ml ¨ Temperature: taken place at room temperature 21 degrees centigrade ¨ Type of substrate used: Hydrogen peroxide ¨ Mass of meat used: 5g ¨ Amount of water in the test tube in which the oxygen bubbles downward displaces in the water. This is so the time taken for each individual bubble to effectively rise to the bottom of the test tube will take the same amount of time.
