Fundamental laws of physics require

Which physical quantity is represented by the ratio of momentum and velocity of the body?

The minimum power required to lift a mass of 50 kg up to a vertical distance of 8 m in 10 s is: (Take g = 10 m/s²)

For every action there is an equal and opposite reaction. The law was given by :

Newton's first law of motion is known as

Force is the product of –
