Question

what is acceleration and what is velocity, intial velocity and what is uniform velocity​

Answer 1

Acceleration that does not change in time is called uniform or constant acceleration. The velocity at the beginning of the time interval is called initial velocity, vi, and the velocity at the end of the time interval is called final velocity, vf.

Answer 2

Acceleration ⸻➤

• Acceleration is defined as the rate of change of velocity. Mathematically, we have a= v-u /t . In SI , it is measured in ms‐².

• The Acceleration is said to be positive, if it is in the direction of velocity and is negative, if it is opposite to the direction of velocity.

Velocity ⸻➤

• velocity is defined as the rate of change of displacement. It is of two types :

1. Uniform Velocity.
2. Non uniform Velocity.

Initial velocity ⸻➤

• when u = 0

Uniform velocity ⸻➤

• A body is said to possess Uniform velocity, if it undergoes equal displacement in equal intervals of time, however small these intervals may be. In such a situation, yhe distance traversed by the body increases with time
