Application of concepts 1. How can you differentiate between a contact force and a force at a distance?
Answers
Answer:
When two bodies that give a force and take the force are in physical contact with each other then the force is said to be contact force. If they have no physical contact, then the force is a non-contact force.
Explanation:
Forces can be attractive or repulsive. These forces can be classified into contact and non-contact forces.
A coconut falling from a coconut tree is an example of a non-contact force. The earth attracts the coconut and it falls towards the earth. There is no physical contact between the earth and the coconut. But still, there is a force of attraction between the earth and coconut. This is an example of a non-contact force.
Pulling a trolley is an example of a contact force. The trolley cannot be made moved if we are not touching it. So there should be physical contact between the two bodies for the contact force to act.
