Final Exam for Motion & Forces Unit

Match the correct law to the correct number

Draggable item		Corresponding Item
Newton's 3rd Law		An object in motion will stay in motion and an object at rest will stay at rest unless an unbalanced force acts on it
Newton's 1st Law		The Force of an object is determined by the mass of the object and its acceleration.
Newton's 2nd Law		Every action force has an equal and opposite reaction

Tractor Trailer

Mini Cooper

Both have the same inertia

A small force is applied to a toy car and it travels a distance of 1.5 meters. If I apply a larger force to the same toy car, what do you predict will happen to the distance traveled by the car.

The car will go just as far (travel same distance)

The car will go farther (travel more distance)

The car will not go as far as before (travel less distance)
