energy transformation

Energy cannot be created or destroyed but it can be transformed.

The sum of all the initial energy = The sum of all the final energy

Kinetic energy is the energy of motion. The faster an object is going, the more kinetic energy it has.

Kinetic energy = half x mass (in kg) x speed (in m/s) squared.

Gravitational potential energy is the energy of height. The higher up an object is, the more gravitational potential energy it has.

Gravitational potential energy = mass (in kg) x gravitational acceleration (10 m/s2 on Earth) x height (in m).

Elastic potential energy is the energy stored in an elastic(or spring) that has been stretched (or compressed). The further it has been stretched, the more elastic potential energy it has.

Elastic potential energy = half x stiffness (in N/m) x extension (in m) squared.

We can use the law of conservation of energy together with the formulas for the various energy types to solve for unknown quantities in a given question.

A hypothesis is a simple educated guess or prediction about a relationship, or outcome that is testable using if and then using then

the thing you change and goe son the x axis

thing you measure

thing you keep the same
