Question

True or False

1. The net force which acts on an object which remains at rest is zero.

2. If two objects are under the influence of equal forces, they have the same acceleration.

3. In order not to slow down, an object moving at a constant velocity needs a small net force applied.

4. An object initially moving at a constant velocity will slow down unless net force is applied.

5. During the collision of a car with a large truck, the truck exerts an equal size force on the car as the car exerts on the truck.

Explanation / Answer

1. The net force which acts on an object which remains at rest is zero. = True.

2. If two objects are under the influence of equal forces, they have the same acceleration. = False. (They can have different masses.)

3. In order not to slow down, an object moving at a constant velocity needs a small net force applied. = False.

4. An object initially moving at a constant velocity will slow down unless net force is applied. = False.

5. During the collision of a car with a large truck, the truck exerts an equal size force on the car as the car exerts on the truck. = True. (Newtons third law says the both forces will be equal in size. Action = Reaction.)
