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.

Why do heavier balls bounce higher?
The air friction is approximately proportional to the square of the radius at high speeds, and to the radius at low speeds. So for bigger balls the ratio of gravitational to frictional force goes up, compared to small balls. That would tend to make the large balls bounce higher.

Why do they 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). As it drops, the ball accelerates and speeds up (Law #2).
How does a ball which falls down bounce back?
When a ball is dropped gravity pulls the ball toward the ground, slowing the ball down so that each bounce is shorter and shorter, until eventually the ball stops bouncing. The force of the ball hitting the hard ground puts an equal force back onto the ball, meaning it bounces back up.See AlsoBouncing Ball PhysicsBouncing Physics: The Science Behind Ball ReboundsSimulating Bouncing Balls: Insights into PhysicsElastic Collisions: Understanding Bouncing Ball Behavior
What energy is used when dropping a ball?
As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy.
Why does a ball bounce physics?
Its velocity and acceleration vectors are pointing the same direction, meaning upward movement. The ball is less deformed than the maximum deformation stage, and due to its elasticity, it is now pushing against the surface with a force greater than its own weight. This is what will cause the ball to bounce upward.
How does the drop height of a ball affect bounce?
If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.
Does mass affect how a ball bounces?
If the mass of the ball increases than the height the ball bounces will increase because the more mass an object has the more energy that gets build up when the ball gets released and makes the ball go higher.

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.
How is baseball physics?
How does temperature affect a ball’s bounce?
One factor that can influence the bounce of a ball is the temperature of the ball. A warmer ball will bounce higher than a cold one. The reason for this is twofold. In a hollow ball, the change in temperature causes a change in air pressure within the ball.
How does Newton’s law of motion apply to basketball?
Newton’s second law of motion is known as Acceleration = Net Force/Mass. This is used in basketball when a player passes the basketball. If they use too much force when passing the basketball, it will go flying past the player it was intended to go to because the mass of the basketball is light.
Can a ball bounce higher than from where it was dropped?
The reason it doesn’t bounce higher than where it started is simple: some of the ball’s energy is lost as heat when it bounces, so it doesn’t have as much going up as it did coming down. Knowing that, you might figure that a ball could never bounce higher than the height from which is was dropped.
Why does steel bounce higher than rubber?
It has different polymers than a rubber ball. Believe it or not, a steel ball actually bounces higher than a rubber ball. When it hits the ground, the steel snaps back faster. The steel is better at storing energy, which helps give it a lot of bounce power.
See also How does the spinning ride work?Why do different types of balls bounce differently?
A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others.
What factors affect the energy of a ball?
The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to the kinetic energy.
Why do balls fall at the same speed?
Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time. Gravity is the force acting in a downwards direction, but air resistance acts in an upwards direction.
Why do balls lose momentum when dropped?
All of the balls lost momentum because there are no perfectly elastic collisions in the real world. Even the most elastic collisions are slightly inelastic. When a ball bounces, energy is transferred to heat, noise or internal energy, which decreases the amount of momentum.
What are the forces that act on the ball?
Answer: The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.
How does friction affect a bouncing ball?
Friction determines the angle of bounce, the horizontal bounce speed, and the spin. It does not affect the vertical bounce, however. Friction acts parallel to and opposite the direction of motion of the ball on the surface. Friction arises whenever a force is applied to move one object across the surface of another.

Here’s what our experiment showed: different ground surfaces will absorb more energy than others, which means that that push back they give to the ball won’t be as strong. A hard surface, like concrete or hardwood, hardly absorbs any, so most of the kinetic energy of the fall goes into bouncing the ball back up.
What is the dependent variable in the bouncing ball experiment?
Because we can drop the ball from any height we choose, the drop height is called the independent variable. But since the rebound height depends on the drop height, the rebound height is called the dependent variable.
How do you calculate ball bounce?
- While the ball is not in contact with the ground, the height at time t after the last bounce at t0 is given by h(t+t0)=v0t−12gt2. where v0 is the velocity just after the bounce.
- During the impact, the ball will deform and there will be friction.
How can the potential energy of a dropped ball be increased?
Before dropping a ball, you must lift it up from its resting surface. When you do this, you are transferring energy from your muscles to the ball and giving the ball potential energy: the higher you lift it, the more potential energy it has.
Do larger balls bounce higher?
The air friction is approximately proportional to the square of the radius at high speeds, and to the radius at low speeds. So for bigger balls the ratio of gravitational to frictional force goes up, compared to small balls. That would tend to make the large balls bounce higher.
