Linear momentum: $$\vec p=m\vec v$$
|
|
$\vec p$ is momentum in kg * m/s
|
|
|
|
# Summary
|
|
* Momentum: $\vec p=m\vec v$
|
|
* It's a vector
|
|
* Doubling either mass or velocity doubles momentum
|
|
* In one dimension, assign positive and negative signs
|
|
* Collision is an interaction where forces between objects are much larger than net external force on system
|
|
* Explosion is interaction where internal forces push parts of a system apart
