A free body force diagram is a diagram showing the forces acting on an object. These are shown as vectors.
Skydiver
- The forces acting on a skydiver are air resistance (acting upwards) and the skydiver’s weight (acting downwards).
Driving car
- The forces acting on an driving car are the driving force, the normal contact force, the weight and friction.
