Q6. Newton's Third Law?
Ans. 
For every action, there is an equal and opposite reaction.
• Newton's Third Law states that for every action, there is an equal and opposite reaction.

• This means that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.

• For example, when you push against a wall, the wall pushes back with an equal force in the opposite direction.

• This law is fundament...read more
