Force is due to Interaction

Last Updated on February 16, 2023 By Mrs Shilpi Nagpal

Question 1 What is meant by saying that force is due to an interaction?

Question 2 Give an example to illustrate that force is due to an interaction?

Interaction

Interaction involves two objects. In Interaction each object act in such a way as to have an effect on the other object.

Interaction of one object with another object results in force between two objects. At least two objects must interact with each other for a Force to come into play. If there is no interaction between two objects, no force can  show its effects.

Suppose a man is standing behind a stationary car, there is no interaction between man and the car, so no force act on the car and hence the car does not move.

No interaction:no force

If the man pushes the car with his hands due to which the car starts moving, there is an interaction between man and a car. During this interaction  force arises which Acts on the car and makes it move in the direction of applied force.

Interaction occurs

If both the objects are capable to applying force on each other, then the interaction between them can be pulling or pushing.

(a) Two boys are interacting and applying force on each other by pushing each other.

(b) The man and cow are interacting and applying force each other by pulling each other.

    Non contact means no attractions like magnetic force is non contact force so it attracts from a distance.
