The ability to do work
What is energy?
Potential energy depends on this.
What is mass and speed?
Mass and velocity
What two things does Kinetic energy depend on?
energy cannot b e created nor destroyed: it can only be transformed from one form to another form. The total amount stays the same.
What is the law of conservation of energy?
0.5 x mass x velocity x velocity
What is the equation for kinetic energy?
Kinetic energy and Potential energy
What are the two types of energy?
At the highest point, potential energy is...
at its most.
At the lowest point
When is Kinetic energy at its most?
Mass x gravity x height
What is the calculation for Potential Energy?
A roller coaster increases its ______ as it travels uphill, and decreases its _______ as it travels downhill.
What is gravitational potential energy?
stored energy gained by compressing a spring or stretching an elastic is an example of this type of energy.
What is elastic potential energy?
A roller coaster increases ________ as it travels downhill, and decreases _______ as it travels uphill.
What is kinetic energy?
A force that resists motion between two touching surfaces.
What is friction?
The type of surface and how hard the surfaces are pushed together.
What amount of friction depends on?
a bow and arrow is an example of this type of energy.
What is elastic potential energy?
