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