1. TRUE or FALSE. Write TRUE if the statement is correct, and FALSE if not. 1. An object at rest will remain at rest unless an external force acts on it. 2. The greater the mass of an object, the more force is needed to accelerate that object. 3. For every action force, there is no equal and opposite reaction force. 4. Uniform circular motion can be described as motion of an object in a circular path. 5. As an object moves in circle, it does not change its direction. 6. The first law of motion of Isaac Newton is the Law of Interaction. 7. The name of the force which is needed for an object to move in uniform circular motion is called Centripetal force. 8. Tension force and gravitational force are examples of Centripetal force. 9. Uniform circular motion as it is related to the First Law of Motion can be used to explain why the planet Earth stays on its orbit as it revolves around the sun. 10. Constant speed means unchanging or no change in speed.​
