Energy
The energy stored by objects ready to be used
Potential Energy
This is how fast an object moves
Speed
force that draws objects to each other or downward toward earth.
gravity
Where does the highest point of the roller coaster?
First hill
Energy of an object in motion
Kinetic energy
A combination of speed and the direction in which an object travels
velocity
A force exerted on an object by the Earth's gravity; on a roller coaster it will make you feel heavy or light with positive or negative of these
g-force
Where is the most kinetic energy on a roller coaster?
bottom of 1st hill
The law that states that energy cannot be created or destroyed
Law of Conservation of Energy
How quickly an object speeds up slows down or changes direction
Acceleration
A push or pull on an object
force
Where is the most potential energy
Top of the first hill
Energy that is directly related to the height and mass of an object
Gravitational Potential Energy
Roller coaster will stay moving in a straight line unless acted upon by an external force.
Inertia
An opposing force that will slow down the roller coaster
friction
Newton's First Law of Energy states?
An object in motion stays in motion unless acted upon by an opposing force
Explain how Law of Conservation of Energy works in a roller coaster
energy is constantly being moved from potential to kinetic and back again.
The speed needed in the top of a loop for an object to make it through the loop without falling
Critical Velocity
To experience weightlessness is known as
To experience a heaviness is know as
negative g-forces
Positive g-forces
If the track of a roller coaster tilts up, where is the gravity applied on the coaster cart?
the back
