True or false if a net force acts on an object, the object's speed will change.
an object's velocity will change if a net force acts on the object.
if two object have the same acceleration, they are under the influence of equal forces.
the net force which acts on an object which remains at rest is zero.
a truck initially moving at a constant velocity will slow down unless a small net force is applied
during the collision of a car with a large truck, the car exerts a lesser force on the truck than the truck exerts on the car.
