What is Newton's first law of motion?
An object at rest will stay at rest, and an object in motion will stay in motion at constant velocity unless acted upon by an unbalanced force.
An object acted upon by an unbalanced force will accelerate in the direction of the force.
The total momentum of a group of objects stays the same unless outside forces act on the objects “including friction.”
What is Newton's second law of motion?
An object at rest will stay at rest, and an object in motion will stay in motion at constant velocity unless acted upon by an unbalanced force.
An object acted upon by an unbalanced force will accelerate in the direction of the force.
The total momentum of a group of objects stays the same unless outside forces act on the objects “including friction.”
What is inertia?
It is the universal Gravitational force.
The tendency of an object to resist changes in its state of motion.
It is a force against motion of an object.
