Name 5 characters in Harry Potter
Harry, Ron, Hermione, Dobby, Draco, Fred, George etc.
Define potential energy
The energy stored in an object
The formula to calculate kinetic energy is
Mass × Gravitational acceleration × Height
False - correct formula is
1⁄2 × Mass × Velocity-squared
Define and give an example of radiation
Radiation is energy that comes from a source and travels through space at the speed of light.
E.g. the sun, stove top, X -Rays
What is the Law of Conservation of Energy?
Energy cannot be created nor destroyed in any chemical reaction. It can only be changed from one form to another.
