What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass of the object and its speed.

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

How does mass affect kinetic energy?

Back

The greater the mass of an object, the more kinetic energy it has if moving at the same speed as a lighter object.

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has. Kinetic energy increases with the square of the speed.

If two objects have the same mass, how does their speed affect their kinetic energy?

Back

The object that moves faster will have more kinetic energy.

What happens to the kinetic energy of an object if its speed doubles?

Back

If the speed of an object doubles, its kinetic energy increases by a factor of four.

What is the relationship between mass and force needed to move an object?

Back

Heavier objects require more force to move than lighter objects.
