An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
This law is often called
"the law of inertia".
A soccer ball will not move until a player kicks it'
Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
You have to push a heavy ball harder to get it to move as fast as a small one
For every action there is an equal and opposite reaction.
