Answer:
1. false 2. True 3.false 4.false 5.false
Explanation:
1. When a certain amount of force is applied on any object that exerts the pressure that is able to compress the substance,then force is able to change the shape
2.less massive object has less inertia and as such would offer less resistance to changes in their velocity. For this reason, a less massive object requires less force to bring from a state of motion to a state of rest.
3. Balanced forces cause stationary objects to stay at rest. However balanced forces would never cause moving objects to stop; an unbalanced force would be required to stop a moving object.
4.If an object stays at rest, there is no net force acting upon it. It just means that all of the forces acting on it are equal in opposite directions. You can look at potential and kinetic energy and the inherent force that gravity exerts on every object.
