Results: On average, the rubber bouncy ball will bounce the highest, followed by the ping pong ball. The marble will bounce the least high.
What size ball bounces the highest?
The results from the experiment showed that the size 3 soccer ball bounces the highest, the size 5 ball bounced the second highest, and the size 4 ball bounced the lowest. In this experiment, it was learned that the smallest foot ball bounced the highest.
What makes a ball bounce higher?
As the ball is dropped and gravity forces it downward, the velocity of the ball increases because of the accelerating effects of gravity. The ball falls through the air, converting stored energy to the energy of motion, and impacts the floor, bouncing higher.
What affects how high a ball bounces?
The size of the ball can affect its bounce due to air resistance, surface volume and density . However, mass can also play a part in how a ball bounces. If two balls contain the same mass, but are of different sizes, the larger ball will bounce less due to greater air friction against its surface.
Which surface is best to bounce a ball on experiment?
A hard surface, such as concrete , absorbs less energy compared with a soft surface, such as a carpeted floor. The more energy absorbed by the surface, the less that remains in the ball for it to bounce.
Which ball bounces higher when dropped together?
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.
Do heavier balls bounce higher?
Both balls will fall at a similar speed, but because kinetic energy is proportional to the mass of the object, the heavy ball reaches Earth with more energy. It will not necessarily rebound higher , as it also needs more kinetic energy to reach a specific height again.
Can a ball bounce forever?
The law of conservation of energy implies that a bouncing ball will bounce forever . Of course, it does not. When you drop it on the floor, it changes some of its energy into other forms, such as heat, each time it hits the floor.
Where does the energy go when a ball bounces?
As the ball falls, that energy is converted to kinetic energy . When the ball collides with the floor, some of this kinetic energy is transferred to the floor and converted to thermal energy (friction) and elastic potential energy (ball deformation.)
Why does a ball stop bouncing?
If you drop the basketball, the force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. ... This is because the basketball had an inelastic collision with the ground . After a few bounces, it stops bouncing completely.
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.
Why do balls bounce higher on concrete?
As the ball is released, gravity pulls the ball downwards and transforms that potential energy into kinetic energy , the energy of motion. The harder the court surface is the more energy a dropped ball retains and the higher it rebounds.
How do you calculate how high a ball bounces?
Between the first and second bounces, the height can be expressed as h = 140 − 16(t − 6.49) 2 , 3.54 ≤ t < 9.45 . The 6.49 is when the highest point is achieved (halfway between the two bounces), and the 9.45 seconds is derived from adding 3.54 seconds to the time between the first and second bounces.
Does mass affect bounce height?
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.
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.
Why doesn’t a ball bounce back to its original height?
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.
