Question

In which case will be more friction between a trolley and the ground -when the trolley is empty or loaded

I think it will be more when it's loaded because
friction is dependent on normal reaction which in this case will depend on weight of body.

Answer 2

Answer:

It was a great answer, ZOOLOGIST, the answer obviously helped me in my physics test, with which I gained 30/30 marks, otherwise, I would fail the 3rd last question and hence, would get 29/30.
