Force Diagrams & Resultant Forces
Science: KS3, topic 3.2.4
Force Diagrams
A force diagram is a diagram showing the forces acting on an object. Forces are shown as vectors.
Skydiver
- Air resistance and weight act on a skydiver.
- Air resistance acts upwards and weight acts downwards.
Driving car
- The driving force and the normal contact force act on a driving car.
- The weight and friction also act on the car.

Which force pushes the car forward when it is driving?
Which of these is true about the forces on a falling skydiver?
According to the force diagrams, which object has more forces acting on it: a skydiver or a driving car?
