PRESENTATION OUTLINE
Acceleration
🚫The rate at which velocity changes🚫
Connection:
When the coaster goes down the hill its acceleration gets bigger.

Force
A lift, a push or pull
Connection:when the roller coaster is going up the hill the force is pulling it up.

Free fall
When the force of gravity is the only thing acting on an object
Connection: when the roller coaster is going down the hill it is free falling.

Power
Force✖️distance
Connection: the roller coaster need power to pull itself up the hill.

Gravity
The force that pulls an object towards the center of the earth
Connection: when the coaster is going down a hill the the gravity is pulling it towards earth.

Friction
THE FOCE WHEN ONE OBJECT RUBS AGAINST another.
Connection: When the wheels on the roller coaster rub on the track.

Kinetic energy
Energy of motion, increases with mass.
Connection: when the coaster is at the bottom of the hill it has Kendrick energy.

Potential energy
Stored energy, increases due to position.
Connection: when the coaster is at the top of the hill it has potential energy.

Centripetal force
A force that causes an object to move in a circle
Connection: when a roller coaster goes on a loop it has centripetal force.

Energy conversion
The process of changing potential energy into kinetic energy.
Connection: when the coaster starts to go down the hill.

Momentum
Mass✖️velocity
Connection:

Newton's first law: something that's in motion will stay in motion until a unbalanced force and a object at rest will stay at rest until a balanced force.
Connection: why your body moves back when the coaster starts to move

Newton's second law: a greater force causes a greater acceleration, the more mass, the more force needed.
Connection: the coaster will go faster with less people in it

Newton's third law: a equal and opposite reaction
Connection: when the coaster pushes down on the track the track pushes back on the coaster

Velocity: speed with direction
Connection: the coasters going 95mph down the hill
