Forces
Indicate whether the following statements are always true or can be false.
True: During the collision of a large truck with a car, the car exerts an equal size force on the truck as the truck exerts on the car.
False: If two object have the same acceleration, they are under the influence of equal forces.
True: The net force which acts on an object which remains at rest is zero.
False: In order not to slow down, a bicycle moving at a constant velocity needs a small net force applied.
False: If an object's speed does not change, no net force is acting on the object.
True: If a net force acts on an object, the object's velocity will change.
