SSC MTS EXAM

Detailed explanation-1: -If an object is moving downwards, then its velocity is described as being downwards. So an airplane moving towards the west with a speed of 300 mi/hr has a velocity of 300 mi/hr, west. Note that speed has no direction (it is a scalar) and the velocity at any instant is simply the speed value with a direction.

Detailed explanation-2: -Earth’s rotation around the Sun, Moon’s orbital motion around the Earth. The vehicle’s speed. How quickly the train is moving. The river is moving at a fluctuating speed. The rate at which water leaves a faucet. The speed at which a bat strikes a ball.
