Give 3 examples, from the lab, where potential energy was converted to kinetic energy.

1. The red ball was potential energy until it was hit by the pendulum converting into kinetic energy.

2. The 5 pounds was a potential energy, until the rope was cut by the scissors, this made the 5 pounds become kinetic energy.

3. The bucket was a potential energy, till the books landed in it causing it to fall, this became kinetic energy
