- Any mass that is moving has momentum.
Momentum (P) = mass (m) x velocity (v)
Momentum is a vector quantiy meaning it has both size and direction.
The conservation of linear momentum states that in any system of interacting bodies, the total momentum is conserved, provided that no resultant external force acts on the system.
Newton's second law of motion states that the applied force is directionally proportional to the rate of change of momentum.
- The conservation of energy law states that energy cannot be created or destroyed, only transferred.
- In collisions, both conservation principles apply, with momentum…
