Forces and Motion

The Forces on a Stationary Car.

What are the Forces on a Stationary Car?

The forces on a stationary car are shown below.
The weight of the car is the force pushing downward on the road.

Forces on a Stationary Car

Newton's third law of motion tells us that the weight of the car
is opposed by an equal and opposite force pushing upward
from the road. The opposing force is called the reactive force.

The forces are balanced and Newton's first law of motion
says that an object that is not moving will remain stationary.
There are no other forces acting on the car.
