1) A ballistic pendulum is a collision in which conservation of energy can be measured. []

2) It's used to measure the velocity of a bullet. []

3) Measurements needed are: mass of pendulum, mass of bullet, height it swings upwards []

4) conservation of energy, kinetic energy, potential energy

Here is an example of how it works.

Here is a second example with a different mass and bullet.

Here is a third examlpe of a ballistic pendulum in action.
