The collision between a basketball and the ground is about 80% elastic so 80% of the kinetic energy is conserved. The other 20% is consumed by thermal energy, which comes from internal frictional forces in the ball and the ground.
Is a basketball elastic or inelastic?
As it bounces back upward, it exchanges its kinetic energy for potential energy, but it does not bounce as high as before because overall, it has less energy. A collision between the basketball and floor will never be perfectly elastic (ideal).
What type of energy does a basketball have?
When a basketball bounces, it has two different types of energy: kinetic and potential. Kinetic is the energy an object has due to its motion. Potential energy is that which is stored in an object—its potential for motion—such as due to its height above the ground.
What objects have elastic energy?
What is elastic potential energy?
- The coil spring of a wind-up clock.
- An archer’s stretched bow.
- A bent diving board, just before a divers jump.
- The twisted rubber band which powers a toy airplane.
- A bouncy ball, compressed at the moment it bounces off a brick wall.
Is a basketball bouncing an elastic collision?
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.
What makes a basketball bounce is it the elasticity of the air or the elasticity of the rubber?
Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape.
What makes a basketball bounce?
Basketballs bounce because of the pressurized air inside of them, gravity and Newton’s Laws of Motion. When you dribble a basketball, your hand and gravity both push the ball towards the ground (Law #1). … The energy in the compressed air is transferred back to the ball pushing it back into motion.
Does a ball have energy?
Lifting a ball into the air before dropping it gives it a type of energy called ‘potential energy’ – which means the ball has the potential to do some work. When you drop the ball, it gains ‘kinetic’ energy (the energy of motion) and loses its potential energy.
When would a basketball player have the most kinetic energy?
When a basketball is held above the ground, it has a lot of potential energy and no kinetic energy. As it falls, it starts losing its potential energy and gets kinetic energy. When the ball hits the ground, it has lots of kinetic energy.
What energy does a bouncing ball have?
Elastic potential energy is what causes a ball to bounce, or rebound, because it is transformed into kinetic energy, which is then used to bring the ball back up.
What objects are stretchy?
The elastic force developed in an elastic object is directly proportional to the external force applied to stretch or compress it.

What type of energy is elastic energy?
Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner.
What has the most elastic potential energy?
Elastic potential energy is energy stored in objects that can be stretched or compressed, such as trampolines, rubber bands and bungee cords. The more an object can stretch, the more elastic potential energy it has.
Is hitting a baseball an elastic collision?
In physics the collision of the bat and the ball is considered elastic. An elastic collision between two objects is one in which the total kinetic energy and total momentum is the same before and after the collision.
What is bouncing a ball called?
A superball or power ball is a bouncy ball composed of a type of synthetic rubber (originally a hard elastomer Polybutadiene alloy named Zectron) invented in 1964, which has a higher coefficient of restitution (0.92) than older balls such as the Spaldeen so that when dropped from a moderate height onto a level hard …
What type of collision does a basketball bouncing on the floor exhibit?
elastic collision: A collision in which all of the momentum is conserved. For example, a ball that bounces back up to its original height.
