Question
The net force on this rugby ball is 0 N0 N. What can we say about the individual forces acting on the ball?
Solution
If the net force on the rugby ball is 0 N, it means that the individual forces acting on the ball are balanced. This could mean one of two things:
- There are no forces acting on the ball at all.
- There are forces acting on the ball, but they are equal in magnitude and opposite in direction, thus cancelling each other out.
In the context of a rugby ball, it's more likely the second scenario. For example, the force of gravity pulling the ball downwards is balanced by an equal force pushing it upwards. This could be the normal force from the ground (if the ball is at rest), or aerodynamic lift (if the ball is in flight).

A force pair is produced when a tennis racket strikes a tennis ball. Which of the following best explains why the tennis ball does not have zero net force acting on it? The forces act perpendicular to each other. The two forces act in the same direction. The force exerted on the ball is greater than that exerted on the racket. Each half of the force pair acts on a different object.
