What is the Law of Conservation of Energy?
The total energy changed into something else
What type of energy is stored in fossil fuels?
Potential Energy
what is rolling friction
resistance of motion caused by a round object rolling across another object
what is Newton's First Law
In object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.
what is static friction
Two objects not in motion due to their contact
What is a Fossil Fuel?
They are fuels formed by once living things
What forms of energy involve the movement of particles or objects?
Mechanical energy, thermal energy, electrical energy, and electromagnetic energy

Newton's First LawIn object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force. unbalanced force when two forces acting on each other cause an object to move.
A fluid is a...
a liquid or a gas.
How does the process of energy transformations relate to the Law of Conservation of Energy?
They both are never lost, they are always conserved
What is a Force?
A force is a push or a pull that involves movement
what is Newton
The unit used to measure a force (N).
what is a balanced force
When forces acting on each other equally and in opposite directions which cause no movement of an object
what is a reference point
A fixed point that you may use to determine if something is moving.
What is a renewable resource?
It is something that it can be used again
what is friction
a force that resists motion by way of contact between two things
what is Newton's Second Law
An object will accelerate, depending on the object's mass, and the forces exserted on the object.
what is momentum
A measure of the motion of an object due to its mass and velocity.
what is average speed
The distance traveled over a certain period of time
What is a non-renewable resource?
A Non-renewable is something that can't be used again
what is sliding friction
a force that resists motion as two things slide across each other
what is Newton's Third Law
For every action force, there is an equal but opposite reaction force
what is inertia
The tendency of an object to resist movement or a change in movement.
what is acceleration
a change in speed or direction
