An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
As long as no unbalanced force acts on an object, it [the object] keeps its speed.

Second Law:
The acceleration of an object depends on the mass of the object and the amount of force applied.
F = MA

Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.
