Question

Define velocity and acceleration ​

Answer 1

Answer:

in a simple way

velocity is rate of displacement

velocity=displacement/ time taken

velocity units are m/s or cm/s

acceleration is the rate of change in velocity

acceleration=v-u/t

acceleration units are m/s^2 or cm/s^2

Explanation:

hope it helps you.

thankyou

Answer 2

Answer:

Explanation:

Velocity:

• The velocity of a body is the distance travelled per second by the body in a specified direction.
• Thus, the rate of change of displacement of a body with time is called the velocity.
• It is a vector quantity.
• S.I unit is m/s and C.G.S unit is cm/s.

Acceleration:

• The acceleration of a body is the rate of change in velocity with time.
• Acceleration = Change in velocity/Time taken.
• Change in velocity means final and initial velocities difference.
• It is a vector quantity.
• S.I unit is m/s²and C.G.S unit is cm/s².
