Question

Draw and example a free body diagram to show all the fource acting on a car

Answer 1

See the diagram above

Let the car be of mass m.
So the gravitational force F=mg, is acting downwards
The normal reaction is acting upwards.
If the car is accelerating at a , the it is moving forward with the force ma.
And the frictional force is acting backwards opposing it's motion.
