define momentum state its SI and CGS units derive the formula for the kinetic energy of an object of mass m moving with velocity
Answers
Answer:
Momentum measures the quantity of motion possessed by a body. It is defined as the product of mass and velocity of the body. Beside magnitude momentum also a direction is the same as the direction of the velocity. The SI unit of momentum is kg-m/s.
In cgs units, if the mass is in grams and the velocity in centimeters per second, then the momentum is in gram centimeters per second (g⋅cm/s).
Let the workdone on the object causes a change in its velocity from u to V and let a be the acceleration. we know that the kinetic energy of a body moving with certain velocity is equal to workdone on the object to acquire that velocity from rest.
hope this helps!
