Centripetal force is a force that makes and object move in a circular path. When an object moves in a circle it can have a constant speed where the magnitude of the velocity is the same but the direction is always changing so the velocity cannot be considered constant. For the velocity to change there must be an acceleration and from there on we can calculate the centripetal force. There are also instances where we don’t know the velocity but we know the time it takes to so from that we can get the velocity of the object that is traveling in the circle. Then by using the laws of conservation of energy we can figure out the height a ball must be dropped from to over come the force of gravity so it can make it around the loop.
In this experiment we set up a Vernier Centripetal Force Apperatus and synched it with the computer to measure the force that it was generating. We measure the force with different masses and at different radii to see how they affected the magnitude of the force. Then after that data was recorded we sent a ball down a track through the loop testing the height the ball needed to be released at so it could make it through the loop with out falling down. The experiment as a whole provided us with a better understanding of centripetal force.
For the first part of the experiment we used the Vernier Centripetal Force Apparatus to calculate the angular velocity of the cart on the end of the rod. First we took the cart off the mass and weighed it obtaining a value of .05kg. Then we attached the cart back to the apparatus and added a 100g mass to it making the total mass of the cart .15kg. Then we adjusted the radius between the cart and center of the apparatus to be .09m. Whe...

...my computed height value I did not take into account the energy lost due to external forces such as friction. To gain more energy to overcome these forces the ball had to be dropped from a greater height so it could make it around the loop. The fraction of the potential energy lost can be found using the equation (actual h-computed h)/(actual h), when we plug our numbers in we find that the fraction of energy lost due to friction and track wobble is .22
The lab was performed as described and using the tools that were provided for us we were able to find the angular velocities and forces for part 1 of the experiment. Then all the percent errors were found and we moved on to part two and used the loop to get a better understand of how energy works and is conserved. The lab did a good job at showing how external factors can throw off your expected results.

- The objective of the experiment was to discover the effect of mass and radius on the centripetal force of a system and determine the mass of a hanging object using the discovered properties. Centripetal force is the culmination of multiple forces that act on a spinning system. By attaching a known mass and changing the radius on between a center post and the unknown mass, the unknown mass can be calculated. Likewise, if the inverse is tested, with a variable known mass and fixed radius, the unknown mass can be calculated.... [tags: Force, Mass, Weight, Mathematics]

- Introduction Sir Isaac Newton once said that to get an object moving it must experience a force. This force will cause the object to move in a certain direction. When an object experiences a force it will move in the direction that the force has created until it experiences the opposite force which will cause it to stop. Newton went on to discover that when objects move in a circular motion that they want to move outwards, away from the centre but still carry on going in a circle. He called this force creating the above movement pattern Centripetal Force.... [tags: centripetal force, experiment]

- In this essay, I shall explore how sketching and prototyping can help in designing an interactive system intended to encourage people to take a walk. In the design process is important to get the design right, and then get the right design (Buxton, 2007). While sketching help in aid to getting the design right, supporting the creative design process and exploring different ideas, prototyping supports choosing the right design, by testing how the product will look like, behave like, and work like (Buchenau & Suri, 2000)....

- Force Force, commonly, a “push” or “pull,” more properly defined in physics as a quantity that changes the motion, size, or shape of a body. Force is a vector quantity, having both magnitude and direction. The magnitude of a force is measured in units such as the pound, dyne, and Newton, depending upon the system of measurement being used. Unbalanced force acting on a body free to move will change the motion of the body. The quantity of motion of a body is measured by its momentum, the product of its mass and its velocity....

- With 86.74m range, Yuriy Sedykh set the world record for hammer throwing. The statement that “The current men’s hammer throw world record will never be broken” is thus false as it is possible to beat the record if certain factors are achieved. Two key factors need to be achieved in order to break the current world record these are the optimal launch angle of 42o must be maintained and the initial velocity of launch must be greater than 29.22m/s. This can be done if the tension (centripetal force) the athlete has on the hammer is greater than 3249.94N and if the athlete can spin an optimal five times before launching....

- Issues investigation Topic: Banking angles Do banked corners make car racing circuits safer. Introduction many car racing circuits around the world have banked corners this is done to increase the traction when the grip level is low, make the racing faster for and more enjoyable for spectators and drivers and it also keeps the water from pooling on the track which stops hydroplaning and the racing teams don’t have to spend as much money on expensive tires. However there are disadvantages to having banked corners like the need of fencing, cars coming back on to the track after crashing, expensive to build and it takes away driver skill....

- “Why is the shape of roller coaster loops not circular?” Introduction: Most of us have been on a roller coaster or at least seen one from a distance. I personally find the vertical loop section the most intriguing section. Surprisingly, none of the vertical loops are actually circular in shape. Instead, it is an almost oval shape. Not to mention, this design was the demand of two very important aspects, namely; safety and thrill. The explanation requires the use of theories of circular motion....

- Comparing and Contrasting Various Forms of Motion in the Observable Universe When one thinks about the different kinds of motion and energy, they may assume that all forms of motion are completely different. On the first day of AP Physics a student will be handed the standard-issue AP equation sheet and be overwhelmed by the sheer amount of individual formulas and think that they have to metamorphosis into a young Albert Einstein in order to understand the material. However, that is a common misconception.... [tags: Classical mechanics, Friction, Force, Mass]

- Introduction: Thrill seekers around the world have engaged themselves in taking part in extreme risky conditions for enjoyment. A majority of these spontaneous people usually do not devote nearly as much time experimenting the safety and the mechanisms behind these adventures as much as they participating in them. A clear example of this situation is the enjoyment of rollercoasters. Thousands of people ride rollercoasters every day. Most of these people would not consider what type of energy it takes to accelerate them and the passengers around them from 0 km/h to over 100 km/h....

- The Physics of Amusement Park Rides The amusement parks we known today have an interesting history, that come from European fairs and pleasure gardens. The Worlds Fair was very influential in the creation of amusement parks. The first Worlds Fair in 1851 held in London began the thought process in creating a fun environment for large exhibitions. With that the first amusement park was born 44 years after the first Worlds Fair. This amusement park was the first enclosed park entertainment area in amusement rides, the infamous Coney Island....
