Why do balls fall to the ground?
When something falls, it falls because of gravity. Because that object feels a force, it accelerates, which means its velocity gets bigger and bigger as it falls. The strength with which the Earth pulls on something in the form of gravity is a type of acceleration.
How differently do different balls fall?
Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
Why do things fall downward?
Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Objects with more mass have more gravity.
Why do balls react different 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. After the collision, the basketball has a very low speed and thus very little kinetic energy.
Why do balls fall at steady speed?
Explanation: As it gains speed, the object’s weight stays the same but the air resistance on it increases. There is a resultant force acting downwards. There is no resultant force and the object reaches a steady speed – this is known as the terminal velocity.
Why do balls eventually stop bouncing?
When the basketball hits the floor, some kinetic energy that the ball has is transferred into another form of energy. This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely. The energy has left the ball!
What is gravity kid friendly?
Gravity is a force of attraction that pulls together all matter (anything you can physically touch). The more matter something has, the greater the force of its gravity. That means really big objects like planets and stars have a stronger gravitational pull.
Where is gravity strongest on earth?
In the case of the earth, the force of gravity is greatest on its surface and gradually decreases as you move away from its centre (as a square of the distance between the object and the center of the Earth).
Why does a ball fall when you let it go?
The short answer to that question is that it’s pulled downward by its weight and it accelerates downward in response to that force. In other words, when you let go of the ball, [SOUND] its weight domainte its motion and it plummets. Well, weight is associated with gravity.
Why do balls bounce when they hit the ground?
Why do balls bounce? 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.
Why does a balloon fall to the ground and a ball?
You’re right: Both the ball and the balloon experience the same gravitational pull. In theory, if they were in a vacuum, they’d fall at the same acceleration and hit the ground at (around) the same time. But this is Earth, and Earth has one major variable that a vacuum does not: an atmosphere, i.e. a “shell” of air.
Why does a tennis ball bounce back up?
The force of the ball hitting the hard ground puts an equal force back onto the ball, meaning it bounces back up. This happens because balls are made out of an elastic material which allows them to be squashed or stretched and then return to their original shape.
