Momentum
- Mass x Velocity
- KGMS-1
- KGMS-1
- Principle of Conservation of Momentum
- In a closed system momentum stays the
same in the absence of external forces.
- In a closed system momentum stays the
same in the absence of external forces.
- Collisions:
- Elastic
- Momentum and KE conserved.
- Relative speed of approach = relative
speed of seperation
- Momentum and KE conserved.
- Ineslastic
- Momentum conserved, KE not.
- Relative speed of seperation is
0/unknown.
- Momentum conserved, KE not.
- Elastic
- Newton's Laws
- 1st: an object will remain at rest /
at a constant velocity unless acted
on by an external force. Inertia.
- 2nd: net force = the change
in momentum of an object.
- 3rd: when two bodies interact, the
forces they exert on each other are
equal and opposite.
- 1st: an object will remain at rest /
at a constant velocity unless acted
on by an external force. Inertia.
- Impluse of a force:
- The area under a force
x time graph
- Force x time
- The area under a force
x time graph
