Kinetic energy
Kinetic energy is the energy which makes objects move or vibrate.
Calculating kinetic energy
Section titled “Calculating kinetic energy”If we know the:
- mass of the object, in kilograms,
- speed of the object, in metres per second,
…then we can calculate the amount of kinetic energy it has!
The formula we use is:
If we put it into symbols, we get:
Where:
is the kinetic energy, in joules, is the mass of the object, in kilograms, is the speed of the object, in metres per second,
