Not all balls are equal. Mass and elasticity affect how high the ball will bounce, and how far it will travel. So does the friction of the surface on which the ball lands. This lesson compares the bouncing of a bocce ball, a tennis ball, and a golf ball. Even a hard rubber ball won’t bounce, if you drop it onto the dry part of a sandy beach.
What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.
Elasticity – Bouncy Balls Apparatus several balls, some bouncy, some not bouncy, steel ball and steel plate or other hard surface to bounce it off, plasticine or blu-tac rolled into a ball. Action The students rank the balls in order of bounciness and explain what makes a ball bouncy.
First you must realize that a rubber ball is an elastic system. It uses elasticity to bounce. In order to have elasticity, it must be able to move around freely. When the temperature drops, the ...
This stage begins the ball’s journey back to where it began. It’s velocity and acceleration vectors are pointing the the same direction meaning upward movement. The ball is less deformed than the maximum deformation stage and due to it’s elasticity, it is now pushing against the surface with a force greater than it’s own weight.
The Effect of Pressure on Elasticity Introduction: An inflated ball is an important part of many sports. The finely tuned reflexes and skills of the athletes is based on the assumption that the ball will behave the exact same way every time. We decided to investigate what affect the inflation level has on the behavior of a ball, what type of ...
This is quite tricky.. How to measure the elasticity of balls using a collision method? apparatus: air track blower gliders motion sensors (2 sets) 2 tennis balls
The air inside the ball puts pressure on the rubber walls, which helps the ball spring back into its original position after it hits the court’s surface and deforms. Topics for Science Class Discussion. What other factors (besides elasticity and air pressure) do you think affect the bounce of a ball? Why?
Collision Elasticity: A tennis racquet's strings are highly elastic and thus exert a strong restoring force on a ball when it impacts the strings, which helps add to the impulse delivered to a tennis ball when it is hit.
The same thing happens when any ball bounces, although it usually happens too fast to be seen by eye. A basketball spends about 20 ms (0.02 s) in contact with the floor which is just enough time to catch a glimpse of the ball squashing.
