How do you calculate how high a ball bounces?
If the first height is h, the second will be f*h, the third f*f*h, the fourth f*f*f*h, and so on.
So if f is 0.9, the first bounce will be 0.9 times as high, the second 0.81 times as high, the third 0.729 times as high (as the original height), and so on.
Try it yourself!.
What can forces do a woman throwing a ball?
Girl throwing a ball: When the girl throws the ball, she is applying a force to it and accelerating it. As soon as she lets go, gravity, which also applies a force, accelerates the ball downward.
How do you make a homemade bouncy ball?
Optional: Disposable rubber gloves.In a cup mix the warm water and the borax.In another cup mix the glue, cornstarch, and food coloring.Pour the glue mixture into the water-borax cup.The glue mixture will harden after 10 seconds; use a fork to take it out of the water. … Roll the mixture in your hands to make a ball.More items…
Is energy conserved when a ball bounces?
Consider the energy. The total energy is constant between bounces if we neglect air friction. We have the kinetic energy of the ball and the potential energy due to gravity. At the top of the bounce, there is no kinetic energy so all the energy is potential.
Are bouncy balls toxic to dogs?
Dogs with strong chompers can bite into a rubber ball as easily as an apple, so a rubber ball might not be a great choice for them if they’re interested in tearing it apart. Ingesting pieces of toys can create internal blockage and serious health issues that could result in a trip to the emergency room.
What is the relationship between drop height and bounce height?
The relationship between drop height and bounce height is only linear for small drop heights. Once a ball reaches a certain height, the bounce height will begin to level off because the ball will reach its terminal velocity.
What energy is used when a ball bounces?
kinetic energyAs the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of an object is the energy it possesses due to its motion.
When a ball drops on the floor it bounces This is according to?
Why does it bounce?; 1) The floor heats up on impact; 2) Newton’s third law implies that for every action there is a reaction; 3) File floor exerts a force on the ball during the impact; 4) The floor is perfectly rigid.

Are the forces acting on the chandelier unbalanced?
Answer. Explanation: The force acting on the chandelier is zero because the chandelier is equilibrium. When the object is in the state of equilibrium it means that an object is balance in all aspect.
Does a ball of glass bounce higher than rubber?
When you drop a ball on a surface, it compresses and squashes slightly, before snapping back to its original shape. … In addition, a solid glass ball will also bounce higher than a rubber ball, but then the trick is finding a surface hard enough to make the ball bounce, but not hard enough to break it!
When you drop a rubber ball on the floor it bounces back?
Explanation: When a rubber ball is dropped on the surface of the floor it bounces back because of the reaction force from the ground on the ball and the elastic force of the rubber which it stores when the ball hits the hard surface and gets deformed.
Why are bouncy balls Bouncy?
The ball can bounce because of the cross-linked polymers. Since the long polymer chains are flexible, when the ball hits the ground, it is able to momentarily deform or squish. The polymers also make the ball elastic meaning it tends to retain its shape.
What factors affect the bounce height of a ball?
The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
Can an object exert a force on itself?
An object cannot exert a force on itself, so as to cause acceleration. If it could, then objects would be able to accelerate themselves, without interacting with the environment. You cannot lift yourself by tugging on your bootstraps.
Why does borax make bouncy balls?
The borax acts as a “cross-linker” to the polymer molecules in the glue – basically it creates chains of molecules that stay together when you pick them up. The cornstarch helps to bind the molecules together so that they hold their shape better.
What are the physics behind bouncing balls?
The ball slows down, deforms temporarily and shoots back up. The air in the ball acts like a spring—it gets compressed and expands again. During the collision, some of the ball’s energy is converted into heat. As a consequence, the ball shoots up with less energy than it had when it reached Earth.
What two forces act on a ball when you throw it?
Answer: The forces on a thrown ball after it leaves the thrower’s hand are the force of gravity and possibly the force of air resistance. The force of gravity at the surface of the Earth is the gravitational acceleration at that location (9.8 meters per second per second) times the mass of the ball.
How do Forces Act to make a rubber ball bounce when you drop it?
The molecules of the floor resist the ball on impact and push the ball back, upward. The actual force acting is due to the forces between molecules that allow the floor to keep its integrity and to prevent the ball from passing through.
Which type of ball bounces the highest?
rubber bouncy ballResults: On average, the rubber bouncy ball will bounce the highest, followed by the ping pong ball. The marble will bounce the least high.
How is bouncing a ball an example of Newton’s third law?
The ball pushes on the floor and the floor responds by pushing back on the ball with an equal amount of force. … The push the ball receives from the floor causes it to rebound, meaning it bounces up. The moving ball again has kinetic energy. This is an example of Newton’s Third Law of Motion: Action/Reaction.
