Energy
This is the energy of motion
Kinetic energy
This is the type of reactions that e=mc2 applies to.
What are nuclear fission and fusion reactions.
This is a major cause of energy consumption in cars and factories.
Friction
These are resources that can be replaced in a relatively short period of time.
Renewable Resource
This is the strongest of the three types of friction
Static Friction
This is the transfer of energy
Work
This is the total potential and kinetic energy of all the microscopic particles in an object
Thermal Energy
As an object increases in height, this increases.
Gravitational Potential Energy
This is energy obtained from free flowing water
Hydroelectric Energy
This is the weakest of the universal forces but acts over the greatest distances
Gravity
This is the energy that is stored as a result of position or shape.
Potential energy
This is a form of energy that travels through space in the form of waves.
Electromagnetic Waves
In a closed system The amount of energy at the beginning of a process and the energy at the end are....
Equal
This is the chemical energy stored in living things.
Biomass energy
This is the strongest of the universal forces but acts over the shortest distances
Strong Nuclear force
This is the potential energy of an object is stretched or compressed.
Elastic Potential Energy
Energy can be kinetic, potential or this
energy produced in fields
This equation indicates that mass and energy are equivalent and can be converted into each other.
E = mc2
Reducing energy use by increasing efficiency and reducing use are examples of this.
Energy Conservation
Action Reaction forces are explained by this Newtonian Law
Newtons Third Law
GPE of an object is always measured relative to the reference level from where this is measured
What is height.
Molten metal contains a great deal of this
Thermal Energy
This is the speed of light and this is its' symbol
c = 3.0x108 m/s
This is often an obstacle to the use of energy efficient products
High initial cost
Newtons First Law is sometimes called this
The Law of Inertia
A car traveling at 100 km/hr will skid this much farther than a car traveling at 50 km/hr
four times as far
If an object has kinetic energy it must also have this
momentum
The ratio of output force to input force of a simple machine is called this
mechanical advantage
A typical gasoline engine is about this efficient
30%
An object at rest may still have this
