2. Momentum, product of the mass of a
particle and its velocity. ...
Momentum is a vector quantity; i.e., it has
both magnitude and direction.
Isaac Newton's second law of motion states
that the time rate of change of momentum is
equal to the force acting on the particle.
Momentum
3. P = mv
P =Momentum
m = mass
v = velocity
Formula of momentum
4. SI unit of momentum
P = mv
P =Momentum
m = mass
v = velocity
mass SI unit - kg
velocity SI unit -
m/s
P =kg × m/s
P = kgm/s
P = kgms-1
6. Second law of motion
According to second law of motion
applied force. change in momentum
