Energy, Motion Force, and Work

Front

What is energy?

The ability to do work or cause change.

Front

What is work in physics?

Back

Force exerted on an object that causes it to move.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate.

Front

What is the relationship between force and motion?

Back

Force causes motion; without force, an object will not change its state of motion.

Front

What happens when two forces act in opposite directions?

Back

The net force is the difference between the two forces, which determines the motion of the object.

Front

What is the unit of work?

Back

Joule (J) is the unit of work in the International System of Units.

Front

How is energy transferred?

Back

Energy can be transferred through work or heat.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.
