Newton’s Third Law of Motion

Collide

To strike or hit something with any mount of force.

Force

A push or pull that can change the motion of an object.

Contact force

Force experienced by bodies when they are in physical contact with each other.

At a distance force

Objects interact due to gravitational, magnetic or electrical forces

Balanced forces

When 2 or more forces action on a object are equal in all direction.

Unbalanced forces

When 2 or more unequal forces action on a object.

Inertia

Tendency of an object to resist change in motion, remains unchanged.

Interacting objects

Objects that effect one another.

System

Regions of space for analysis.

Newton(N)

Unit of measurement for force

Newton’s Law of Action Reaction (3rd law)

For every action there is an equal and opposite reaction.

Newton’s Law of inertia (1st law)

An object at rest will stay at rest. So object in motion will stay in motion unless acted on by an unbalanced force
