force chapter explanation
Answers
Answer:
In science, the word 'force' has a precise meaning. ... A force is exerted on one object by another. The idea of a force is not limited to living things or non-living things. All objects (living and non-living) can apply a force on or to another object; also all objects (living and non living) can be affected by forces.
FORCE
A force is a push or pull that causes a change in speed, direction or shape. Newton's third law says that for every action there is an equal and opposite reaction. This means that when one object pushes on another with a force, the other object pushes back on the first object with the same force.
Force is defined as an external cause that changes or tends to change the state of the body once applied, if the body is in motion it comes to rest and if at rest then will come to motion. ... Example: Pushing or pulling a door by applying force.
