a free body diagram of a car slowing down would typically include the following elements:
The car, represented by a rectangle or square
The ground or road, represented by a horizontal line or plane
An arrow pointing downward representing the force of gravity acting on the car
An arrow pointing horizontally to the right representing the force of friction acting on the car
An arrow pointing horizontally to the left representing the applied force or deceleration of the car
The diagram would also include any other relevant forces, such as air resistance or the force of the brakes, represented by additional arrows. It is important to label each force with its magnitude and direction to understand the forces acting on the car and how they affect its motion.
