Term
| momentum depends on what two things? |
|
Definition
|
|
Term
|
Definition
p=mv
momentum equals mass times velocity
p=kg*m/s |
|
|
Term
| Law of conservation of momentum |
|
Definition
| total amount of momentum of group of objects does not change unless outside forces(friction) act on the objects. therefore, when the object hits each other they transfer their momentum to each other |
