Newton's Laws of Motion Quiz

Which of the following is not one of Newton’s 3 Laws of Motion?

• When an object exerts a force on a second object, the second object exerts a force with equal strength on the first object, but in the opposite direction

• The acceleration of an object depends on the force exerted on it and its mass

• An object at rest will stay at rest, and an object in motion stays in motion with a constant velocity unless acted on by an unbalanced force

• The sum of all forces acting on an object is equal to net force.

If Newton’s 2nd law states that F = m X a, which of the following is TRUE?

• An object with a larger mass will have a greater force

• An object with a smaller mass will have a greater force

• An object with a smaller acceleration will have a greater force.

• An object’s mass and acceleration has no effect on the object’s force
