What does Newton's second law of motion state?
Force equals mass times acceleration.
For every action, there is an equal and opposite reaction.
An object in motion stays in motion unless acted upon by an external force.
The velocity of an object does not change unless acted upon by a net force.
If the mass of an object increases while the applied force remains constant, what happens to the acceleration?
Acceleration increases.
Acceleration decreases.
Acceleration remains the same.
Acceleration becomes zero.
What happens to the acceleration of an object if the net force acting on it doubles while its mass remains unchanged?
Acceleration halves.
Acceleration remains the same.
Acceleration doubles.
Acceleration quadruples.
