ROLLERCOASTER VOCAB CURATION

NEWTONS FIRST LAW

• AN OBJECT IN MOTION (OR AT REST) WILL TEND TO STAY IN MOTION (OR AT REST) UNTIL ACTED UPON BY AN OUTSIDE FORCE
• I chose this picture because the people are being pushed back from inertia.

NEWTONS SECOND LAW

• A GREATER FORCE CAUSES A GREATER ACCELERATION, THE MORE MASS, THE MORE FORCE NEEDEDR
• I chose this picture because the greater force exerted by the coaster the more acceleration the carts will go.

ACCELERATION

• A CHANGE IN SPEED OR DIRECTION
• I chose this picture because the coaster changes direction a lot.

CENTRIPETAL

• A FORCE THAT CAUSES AN OBJECT TO MOVE IN A CIRCLE
• I chose this picture because the coaster is looping with centripetal force.

ENERGY CONVERSION

• THE PROCESS OF CHANGING ONE FORM OF ENERGY TO ANOTHER
• I chose this picture because at the start station there is pe and when it starts it turns into ke.

FORCE

• TO PUSH OR PULL OR LIFT
• I chose this picture because the coaster exerts force to get the people to the top.

FREE FALL

• WHEN GRAVITY IS THE ONLY FORCE ACTING ON AN OBJECT
• I chose this picture because the coaster is going strait down and gravity is the only force acting upon it.

NEWTONS 3RD LAW

• For every action there is an equal and opposite reaction
• I chose this picture because the cart exerts force on the coaster and the coaster does the same thing back to it.

FRICTION

• The force that one surface exerts on another when two things rub together.
• I chose this picture because the coaster uses friction to maintain a specific speed

GRAVITY

• The force that pulls objects toward earth.
• I chos this picture because grvity helps the cart go downhill.

POTENTIAL ENERGY

• Energy that is stored and held in rediness.
• I chose this picture because at the top of the hill, there is a split second of PE

KINECTIC ENERGY

• The energy of motion.
• I chose this picture because there is alot of KE used when the coaster is going.

VELOCITY

• Speed with direction
• I chose this picture because there is a ton of velocity because of the turns.
