Observe that each of the collisions above involve the rebound of a ball off a wall. Observe that the greater the rebound effect, the greater the acceleration, momentum change, and impulse. A rebound is a special type of collision involving a direction change in addition to a speed change. The result of the direction change is a large velocity ...
Two balls of equal mass (one red and the other yellow are dropped from the same height and rebound off the floor. The red ball rebounds to a higher position. Which ball is subjected to the greater magnitude impulse during its collision with the floor? (a) It's impossible to tell since the time intervals and forces are unknown.

Oct 2, 2014 · When a ball is thrown onto a wall, the ball exerts a force onto the wall. According to Newton's Third Law, the wall will exert an equal and opposite force to the ball. Thus, how would the ball be able to bounce back? Shouldn't it just slide down the wall? newtonian-mechanics. forces. momentum. conservation-laws. collision. Share. Cite.
- You have to consider this as a dynamic process. To make sense of it you also have to think of the ball as NOT a point particle, so it has a centre...
- The forces don't anulate each other because they are not on the same body. The ball creates a force F on the wall. Then, according to the Newton's...

When a ball is dropped to the ground, one of four things may happen: It may rebound with exactly the same speed as the speed at which it hit the ground. This is an elastic collision. It may come to a complete rest, for example if it were a ball of soft putty. I shall call this a completely inelastic collision.
Feb 26, 2016 · Record the rebound of the ball in slow motion and use the measuring device to calculate the distance traveled by the ball. Then, use the formula a = (vf - vi) / t to calculate the acceleration, where vf is the final velocity, vi is the initial velocity, and t is the time taken for the rebound.
ditions and the functional form of the force acting on the ball. If the collision is elastic, then the force, F, acting on a ball during the collision is given approximately by Hooke’s law, F5kx, where x is the ball compression. The collision can then be modeled as one between two springs.1 The spherical geometry introduces a complication ...
Bouncing Ball Experiment. GCSE Science. Alex Boorman Ph10 - - Aim: To find out what affects the height to which a ball bounces. Variables: Height from which the ball is dropped. Mass of the ball. Material ball is made from. External factors, i.e. changing air density, temperature. The surface onto which the ball falls.
