Thrust- opposite to the direction of motion -
An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
The relationship between an object's mass m, its acceleration a, and the applied force F is F=ma acceleration and force are vectors.
For every action there is an equal and opposite reaction.
