Question
Write a note an momentum.
✓
Answer
Momentum of a particle is defined as product of mass with velocity. It is denoted as $\vec{p}$
Momentum is also a vector quantity
$
\overrightarrow{ r }= m \overrightarrow{ v }
$
The direction of momentum is also in the direction of velocity, and the magnitude of momentum is equal to product of mass and speed of the particle.
$p = mv$
In component form the momentum can be written as
$
p _{ x } \hat{i}+ p _{ y } \hat{j}+ p _{ z } \hat{k}= mv _{ x } \hat{i}+ mv _{ y } \hat{j}+ mv _{ z } \hat{k}
$
Here,
$p _{ x }= x$ component of momentum and is equal to $mv _{ x }$
$P_x=y$ component of momentum and is equal to $mv _{ y }$
$P_x=z$ component of momentum and is equal to $mv _{ z }$
