Question

EXPLAIN VELOCITY....... ​

Answer 1

Answer:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north

Answer 2

• The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time.
• It might sound complicated but velocity is basically speeding in a specific direction.
• It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity.
• The SI unit of it is meter per second (ms-1).
• If there is a change in magnitude or the direction in the velocity of a body the body is said to be accelerating.
• Initial velocity describes how fast an object travels when gravity first applies force on the object.
• On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.
