DESCRIPTION The Centripetal Acceleration lab consists of using a pendulum bob swinging continuously. This will help see the F_max(tension) and F_(mean )(weight of the pendulum)‚ net force (N) and v_mean(velocity). RESULTS When starting the lab the first thing to do is to measure the cylinder properties (the bob) in table one. The measurements were: diameter (D) is .0815m‚ height (H) is .025 m‚ mass is .06591 kg‚ and the 〖Weight〗_theory W is .645918 Mg‚N. Second thing to do is to launch from

the acceleration due to gravity (or g) is approximately 9.8m/s2 [down] or -9.8m/s2 [up]. What we are trying to do is design an experiment to measure and confirm this value. Our plan was to drop an object from a reasonable height and use a ticker tape timer to measure the amount of time and distance travelled between each time. The weight of the object used would have to be heavy enough that it would not be affected by air resistance. For example‚ you shouldn’t use a piece of paper because due to

HSC Physics Notes - Space 9.2 - 1. The Earth has a gravitational field that exerts a force both on it and around it 1. define weight as the force on an object to a gravitational field Mass is the measure of how heavy an object it. Every object has a mass which is static and does not change with any force exerted on it or from it. However‚ weight is the force which is exerted upon an object when it comes into contact with or nearby a gravitational field of some strength. Weight is a force ஃ a vector

the objects with different masses to fall equal distances was equal. 2. The average speed of the two different masses was quite similar‚ within one tenth of a second of each other. 3. Yes‚ because physics theory says that objects free falling‚ where the only force acting on them is gravity‚ accelerate at the same rate no matter what their mass is. 4. The change in spacing of the dots tells us that the speed of the object is increased as it falls‚ because the spacing increases between the

Gabriel-Ohanu Emmanuel PARTNER: Baptiste Gilman TITLE: Graph Matching PURPOSE: The purpose of the experiment was to analyze the motion of a student walking along a straight line in front of the motion detector moving back and forward with different speed trying to match the graph provided. To also understand and interpret graphs of distance vs time and velocity vs time. To also know what the slopes of the each graph represent which tells how far the student travelled‚ the speed and whether

The point where the centripetal acceleration is provided completely by gravity is when the centripetal acceleration is equal to the gravity. This happens at the point where h=r/2. As the truck moves from point A to point B‚ it would have decreased in height by r. Applying this again to our equation‚ we get; Hence‚ Using this in our g-force equation‚ we get; And so the rider experiences an additional 2g of centripetal force from that experienced at the top. Later‚ as the tuck moves to point
