Back

A force is a push or pull acting on an object, which can cause it to change its velocity.

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the relationship between speed and kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy is converted to kinetic energy.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.
