★ Newton's Third Law of motion ★
- To every action there is equal and opposite reaction. Such that when we are walking on the ground , walking is a action , Force of friction acts between the ground and our legs (is a reaction).Hence motion is possible in this case .
★ Numeracaly Second Law of Motion ★
➸ Force ∝ Change in momentum / Time
➸ Force ∝ (mv - mu)/t
➸ Force ∝ m(v- u)/t
➸ Force ∝ ma
➸ Force = k × ma
- k is constant proportion.
➸ Force = ma.
