Question

Name the type of force involved in the following:-

Leaf falling from a tree

A person diving in a pool

A worker pulling a cart on a levelled load.​

Answer 1

Answer:

leaf falling from a tree - gravitational force (and air resistance)

a person diving in a pool - A diving person falls into the water by the gravitational pull. Once inside the water, the gravitational pull is overcame by the buoyancy of the water. This results into an unbalanced force which prevents one from reaching the floor of the swimming pool. The buoyancy of water equals the upthrust.

a worker pulling a cart on level road - frictional force
