CLASS IX SCIENCE ASSIGNMENT
Ch-9: Force and Laws of Motion
1. If a body is in motion, is it necessary that it is being acted upon by a force​

Answer 1

Answer:no

Explanation:it is not necessary that the body will be acted by an external force.

From newton's 1 law of motion a body remains in motion unless an external force is applied

Hence this body will also remain in motion unless an external force such as friction or tension is applied
