Question

In which case will there be more friction between a truck and the road; when the truck is empty or when it is loaded?

Answer 1

1. Friction can be increased by increasing the weight of the moving body.
2. As a result, there will be a better grip between the surface and the body.
3. So when the truck is loaded, there will be more grip between the road and the truck.
4. Hence, a loaded truck will offer more friction than an empty trick.
