eg. a truck of mass 200kg is moving with a velocity 10m/s. What is its momentum

sol. m= 200kg

v=10m/s

momentum,P = mv

=200x10

=2000kg-m/s

**momentum is a product of the mass and the velocity of the object. the momentum changes very time when the mass or the velocity of the object changed.**

**example : a cycle of mass 60 kg's including the person sitting on it moves with the velocity 15 meters per second. find out the momentum of the object ?**

**solution : mass = 60 kg**

**velocity = 15**

**to find out momentum of the body we should use the formula p = mv**

**in the formula p means momentum of the body, m is the mass and v is the velocity.**

**p = mv**

**p = 60*15**

**p = 900 meters per second.**
