Forces acting on an object

05holtel

1. Homework Statement

1) Identify all of the forces acting on you as the car travels at a perfectly steady speed on level ground

2) Repeat part 1 with the car slowing down.

2. Homework Equations

N/a

3. The Attempt at a Solution

1)The forces acting on the car at constant velocity include:
A normal force, gravitational force, the applied force of the car, Force of friction

Please note that in order for the car to travel at constant speed, Normal Force = Gravitational Force, and the applied force of the car = Force of friction

2) The forces acting on the decelerating car include
A normal force, gravitational force, Force of friction

Is this correct?

In the second situation, there is still a force that is the car is applying ; It is simply less than the frictional force.

Wouldnt the gravitational force and normal force just cancel each other out because the car is not moving up or down into the road...?

Mattowander

They would cancel each other out, but you still have to list them as forces acting on the car.
