Force
Define force
The push or pull on an object with mass causes it to change its velocity.
define motion
the action or process of moving or being moved
which of newtons laws is this: an object will not change its motion unless an outside force acts on it.
Newton's first law

speed
What is the formula for acceleration
A= v/t
What is the formula for force?
Force = mass * Acceleration
what is it called when a object is not in motion?
