Force and Motion

Front

What is force?

Back

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

Front

What is motion?

Back

The change in position of an object over time.

Front

What is gravitational force?

Back

The attractive force between two objects due to their mass.

Front

What happens to gravitational force if the mass of one object is doubled?

Back

The gravitational force increases.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

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.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity is speed with a direction.

Front

What is friction?

Back

The force that opposes the motion of an object in contact with a surface.
