# 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.

#### jessica.so

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.
