Energize me
The ability to do work or cause change
What is energy?
Potential energy that depends on the height of an object
What is a force?
this scientist created 3 important laws of motion
Who is Isaac Newton?
A change from one form of energy to another
What is energy transformation?
a slanted surface along which a force moves an object to a different elevation
What is an inclined plane?
stored energy that results from the position or shape of an object
What is potential energy?
Equal forces acting on an object in opposite directions
What are balanced forces?
Force equals mass times acceleration
What is Newton's second law?
The total energy of motion in the particles of a substance
What is thermal energy?
A simple machine that consists of a rope that fits into a groove in a wheel
What is a pulley?
the energy an object has due to its motion
What is kinetic energy?
Forces that cause a change in the motion of an object
What are unbalanced forces?
For every action there is an equal and opposite reaction
What is Newton's 3rd law?
The direct transfer of heat from one substance to another substance that it is touching.
What is conduction?
a simple machine that consists of a bar that pivots at a fixed point called a fulcrum
What is a lever?
the amount of work an object can do because of the object's kinetic and potential energies
What is mechanical energy?
total distance divided by total time
What is average speed?
An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
What is Newton's first law?
The transfer of heat by the movement of a fluid
What is convection?
A doorknob is an example of this simple machine
What is a wheel and axle?
Potential energy that depends on the height of an object
What is gravitational potential energy?
the standard international unit of force
What is the Newton?
The tendency of an object to resist changes in motion
What is Inertia?
when two objects are at the same temperature and no heat flows
What is thermal equilibrium?
This machine is essentially a long inclined plane wrapped around a shaft.
What is a screw?
