Unit for work (metric) is a _______.
a speed in a particular direction.
displacement in the y-axis; dy
(physics) a rate of change of velocity
a force acting upon an object to cause a displacement. (key words: force, displacement, and cause)
law of conservation of energy
energy can not be created or destroyed. it can be transformed from one form into another, but the total amount of energy never changes.
(physics) the force of attraction between all masses in the universe
Chemical energy
energy stored in chemical bonds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by product.
chemical energy and gravitational energy
What are two forms of potential energy?
cause change
What can energy cause?
mass and velocity
Kinetic Energy depends on what?
elastic energy
a mousetrap is an example of what type of energy?
it increased
If a train's velocity goes from 25mph to 50mph and it's mass remains the same, what happened to it's kinetic energy?
energy transformation
A change from one form of energy to another is called_______
Potential to Kinetic
Ex. a stretched rubber band is released!
A freight car moves along a frictionless level railroad
Gravitational constant
