WHAT IS NEWTON

The Unit of force is Newton(N).

Newton is the amount of force required to produce 1m/s^2 acceleration in 1 Kg body.

Force is a Vector Quantity.

WHAT IS MOMENTUM

Momentum is the product of mass and velocity.

p =mv

Momentum is a vector quantity

5 of 9

UNIT OF MOMENTUM

Since it is product of mass and velocity.

m = kg

v= m/s

So,

The unit of Momentum is,

kgm/s

Example#01

A car of mass 800 kg is moving with velocity of 2 ms . Calculate its momentum

Solution

Given data:

mass of the car = 800kg

Velocity of the car = 2m/s^2

Momentum =p=?

momentum = mass x velocity

p=(800)(2)

p = 1600kgm/s

Example#02

A 60kg object is moving at a velocity of 5 meters per second. What is its momentum?

Given data:

mass of the object = 60kg

Velocity of the object = 5m/s^2

Momentum =p=?

p = mv

p = (60)(5)

p= 300 kgm/s
