Question

Why do the back wheels of a cart go over a bump easier than the front wheels?

In: Physics

Answer 1

Leverage. When the front wheels of a cart go up, the cart turns into a lever and the front wheels want to go up and back. Whereas the back wheels go up and forward because the cart is pivoting on the front wheels.

So pushing the back wheels of a cart up a bump is also pushing it forward.
