Energy and Motion (Kinetic and Potential Energy)

Vocabulary

1) Work – when an object moves a certain distance

2) Energy – ability to do work or cause change

3) Kinetic energy – energy an object has due to its motion (moving energy) (dependent upon mass & speed)

4) Potential Energy – stored energy resulting from position or shape of an object

5) Energy transfer examples (potential to kinetic to surrounding objects)

6) Conservation of energy – energy cannot be lost or destroyed, only transferred

7) Mass – the amount of matter or particles in an object (related to density)

8) Acceleration – the rate at which velocity changes

9) Motion – an objects change in position over time

10) Force – the energy from a physical action like a push or pull

11) Mechanical Energy – the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.

12) Thermometer – an instrument used to measure how cold or hot an object is.
