Force, work, and motion

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as Work = Force x Distance.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is potential energy?

Back

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