100
The energy an elastic band has when it's stretched.
What is potential energy?
100
Used to chop down a tree.
What is a wedge?
100
A push or a pull.
What is a force?
100
This law explains why bumper cars need a push to start and why they keep moving in one direction unless they are bumped by another car.
What is Newton's first law (Inertia)?
100
This shape is what cuts down on the friction between the car and the air (air resistance)
What is streamlined?
200
The energy a car has when driving along the road.
What is kinetic energy?
200
A wheelchair ramp.
What is an inclined plane?
200
A force that resists the movement (makes something gradually stop moving).
What is friction?
200
An example of this is when a ball bounces off the ground.
What is Newton's 3rd law?
200
This force is used to stop the drop on the Giant Drop.
What is magnetism?
300
The two types of energy the sun produces.
What are heat and light energy?
300
A simple machine used to raise a flag.
What is a pulley?
300
The act or process of changing place.
What is motion?
300
This law explains why more force is needed to kick a medecine ball than a balloon.
What is Newton's 2nd law?
300
This is what is happening when the car starts down the hill.
What is acceleration?
400
The energy that is released from food (after it's been eaten).
What is chemical energy?
400
An example of this simple machine is a spiral staircase.
What is a screw?
400
The force that attracts two objects with mass together (i.e. A chair and the floor).
What is gravitational force?
400
This law explains why loose objects in a car will continue to move when a car hits a wall.
What is Inertia?
400
On a rollercoaster this changes through each part of the turn. It's the direction it takes before, during and after the turn.
What is velocity?
500
The energy used by plants for photosynthesis.
What is light energy?
500
A simple machine used to gather fallen leaves.
What is a lever?
500
The rate that speed or direction changes.
What is acceleration?
500
This law explains why when we step off a boat (floating in water) onto shore, the boat moves in the opposite direction.
What is Newton's 3rd law?
500
These are used in rollercoasters for acceleration and deceleration. They are carefully planned to control the speed of the rollercoaster.
What are hills?
