Front

What is Newton's 3rd Law of Motion?

Front

What force attracts objects towards each other, like you and the Earth?

Back

Gravity.

Front

What is inertia?

Back

An object's resistance to change in motion.

Front

What happens when an unbalanced force acts on an object?

Back

It changes the motion of the object.

Front

What is the combination of all the forces acting on an object called?

Back

Net force.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is momentum?

Back

The quantity of motion an object has, calculated as mass times velocity.
