Answer 1

• Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time.

Answer 2

Answer:

According to the velocity meaning, it 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 of velocity of a body, then it is said to be accelerating.

Initial and Final Velocity

1. Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand,
2. the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.
