What happens when a falling object hits the ground?
When an object falls toward Earth, it accelerates due to the force of gravity, gaining speed and momentum until the upward force of air resistance exactly balances the downward force due to the object’s weight under gravity – a point referred to as terminal velocity.
Why does a ball bounce back when it hits the ground?
Answer. When the ball falls from a certain height than it gains an amount of potential energy which is very instant converted into kinetic energy , that energy helps the ball in bouncing back.
How does a bouncing ball lose energy?
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.
Why does the height of a bouncing ball decreases after each bounce?
The ball has the force of gravity, which is conserved while traveling down towards the ground. While it is traveling the potential energy is being transformed into kinetic energy, which demonstrates a conservation of energy. However, the total energy, KE + PE decreases with each bounce of the ball.
Does a ball bounce higher if it drops a greater distance from the ground?
Thus a typical ball bounces to 60% of its original height because it stores and returns 60% of the energy it had before the bounce. When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.
Why do the balls react differently when you drop them together?
Both the basketball and the tennis ball are moving at the same speed right before they hit the ground. This means they both have some amount of kinetic energy, but the basketball has more due to its larger mass. With different mass balls, the final speeds of the two balls will also be different.
