You drive round a bend once at 30 km/h and again at 60 km/h. How does the centrifugal force change?

In the scenario of driving around a bend, the centrifugal force you experience is affected by your speed. The centrifugal force increases with the square of the velocity. This means that if you double your speed, the centrifugal force does not just double; it actually increases by a factor of four.

When you drive at 30 km/h and then at 60 km/h, the force changes as follows:

- At 30 km/h, the centrifugal force is based on that speed.
- At 60 km/h, which is double the speed, the centrifugal force becomes four times higher because of the speed squared relationship.

Understanding this is essential for driving safety. Higher centrifugal force can lead to loss of control, especially in bends, which is crucial knowledge for drivers to adhere to traffic regulations and ensure safe maneuvering on the road.
