__**Law of Inertia: **__** " An object at rest will stay at rest unless an external force is applied" ** When you are standing on the ground before the beam you are inert (stationery), you will stay inert unless you force yourself onto the beam.

__**Law of Acceleration: **__** "The Acceleration of a body/object is proportional to the faorce acting upon it" ** e.g. Force=Mass times Acceleration The faster and harder you run and jump onto the vault, the higher and further you will go.

__**Law of Action/Reaction: **__** "For every action, there is an equal and opposite reaction" ** Action... pushing down into the vault. Reaction...Springing up higher in the air to be able to land on the beam.

 * Law of Inertia ** : 0:09 - The girl is stationary. She then uses her legs to force herself up onto the beam. Therefore she wouldn't have moved from the spot until she forced herself or an external force was applied e.g someone pushing her.

**Law of Acceleration**: 0:04 - The girl runs at a fast speed in order to gain the momentum to allow her to gain the height needed to get onto the beam.

**Law of Action/Reaction**: 1:46 - The girl runs at the vault, as she hits the vault her feet push down on to the board which allows her to spring up into the air to then land on the beam.
