Key Takeaways

KEY TAKEAWAYS

• Momentum depends on the mass and velocity of a system; it is proportional to both components.

• Impulse is the amount of force applied over a specific period of time or the change in momentum.

• Impulse and momentum are vectors with direction and magnitude.

• In collisions between two objects in one or two dimensions, there will be conservation of momentum and kinetic energy in elastic situations but just conservation of momentum in inelastic situations.
