Collisions and kinetic energy
Momentum is always conserved, kinetic energy only sometimes. Compare kinetic energy before and after to tell an elastic collision from an inelastic one, then analyse trolley and light gate data.
You will be able to
- Calculate the kinetic energy transferred in a collision
- Decide whether a collision is elastic
- Analyse light gate data to test conservation of momentum
