_________ is Active energy; the energy associated with the movement of objects. Anything that is moving has _________.
Kinetic Energy
Potential Energy
Gravitational Energy
Mechanical
The formula for Kinetic Energy is:
KE = ½ mv2
KE = FD
KE = 1/2 FD2
KE = M x A
_________ is the energy due to an object’s position above
the earth’s surface.
Mechanical
Gravitational
Kinetic
Chemical
________ Is energy stored in elastic materials such as a spring (when it’s compressed) or elastic object (when it’s stretched).
Gravitational Potential Energy
Mechanical
Elastic Potential Energy
Chemical
The amount of elastic potential energy stored is related to the amount of stretch of the object; the more stretch the more energy.
True
False
"For some springs, the amount of force is directly proportional to the amount of stretch or compression, the constant of proportionality is known as the spring constant (k)" Describes which law?
Planks
Hooke's
C
E=MC2
A type of potential energy stored in the bonds between elements of a substance (remember studying bonds in chemistry).
Mechanical
Gravitational
Kinetic
Chemical
_______ is stored in the nucleus of an atom.
Nuclear Energy
Potential Energy
Chemical Energy
Magnetic Energy
Nuclear fission produces energy through the splitting of atoms, which releases heat that can then generate steam and be used to turn a turbine to produce electricity.
True
False
Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and joining to form a new type of atomic nucleus.
True
False
A type of kinetic energy contained within a substance due to the movement of molecules.
Mechanical
Chemical
Thermal
Gravitational
What is the formula for work?
F = M(A)
KE = 1/2M (V)2
W = F(D)
Power = W/T
States that energy cannot be created or destroyed,
only transformed/transferred.
Newtons 2nd Law
Gravity
Law of Conservation of Energy
Law of Thermodymics
For a force to qualify as having done work, there must be a
displacement and the force must have caused the displacement.
True
False
