What is the second law of motion?

• The state of motion of an object does not change as long as the net force acting on the object is 0.

• Friction causes an object to slow down and affect the motion.

• The acceleration of an object is equal to the net force acting upon it divided by the object’s mass.

• The measure of inertia relative to the object’s mass is the object’s acceleration.
