Answer:

Gravitational force, electrical force, magnetic force, VanderWaal force

a person throwing a ball or writing on paper

Friction

elastic potential energy

Tenda

Explanation:

Gravitational force, electrical force, magnetic force, VanderWaal force, nuclear force. These are forces of nature that act at a distance.

Some examples for contact forces are a person throwing a ball or writing on paper. The contact forces are push, pull and friction. Some examples for non- contact forces are a magnet and a paperclip and the moon's gravity and the earth's tides.

Friction is the force that acts between the two surfaces that are sliding, or trying to slide, across each other.

You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy.

Tenda is a traditional system utilized for drawing water from the open wells. It functions on the simple principles of lever.
