Questions

Question 1 Multiple Choice (Single Answer)

According to Newton's First Law of Motion, an object at rest will remain at rest, and an object in motion will continue moving with the same velocity, unless acted upon by an external force.

  1. True
  2. False
Question 2 Multiple Choice (Single Answer)

The measure of an object's resistance to changes in its motion is called:

  1. Mass
  2. Weight
  3. Momentum
  4. Force
Question 3 Multiple Choice (Single Answer)

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass.

  1. True
  2. False
