Force transmitted through a string, wire, rope, and or cable when objects are at both ends

An object persists in uniform motion in a straight line unless disturbed by an unbalanced force

What external force causes a vehicle's forward motion?

What happens to the acceleration of an object if the mass is increased by 4 & force constant?

Action & reaction forces do not cancel each other because...

Force created when a large object (like a planet) attracts another toward it.

What causes an acceleration?

Diagram used to visualize the magnitude and direction of all forces acting upon an object. 

For every action, there is an equal and opposite reaction

Why do action-reaction pairs not cancel each other out?

The sum of all forces acting upon an object is known as:

Forces only exist as a result of an interaction.
