Momentum

MOMENTUM:

“Momentum is qualitatively defined as the quantity of motion present in an object.”

OR

“Momentum is quantitatively defined as the product of mass and velocity of an object.”

• Momentum tells us the impact of force when two bodies come in contact with each other.

• Greater the mass, greater will be the momentum. Similarly faster the speed, greater will be the momentum.

• It is a vector quantity.

• It is represented by $p$.

Formula:

$Momentum \thinspace = Mass \thinspace X \thinspace Velocity$

OR

$\boxed {p = mv}$

S.I Unit:

$Momentum \thinspace = Mass \thinspace X \thinspace Velocity$

Multiply and Divide by “$s$”:

$= (Kg) \thinspace (\frac{m}{s}) (\frac{s}{s})$

$= (Kg) \thinspace (\frac{m}{s^2}) {s}$

Since, $(Kg) \thinspace (\frac{m}{s^2}) = N$

$\boxed {Momentum (p) = Ns}$
