Work
This is the amount of force applied over a certain distance or _____ = Force x distance
What is Work
This the rate at which work is done or _______ = Work/time
What is Power
This is the amount of stored energy in an object based on it's height or ______ = m * g * h
What is Potential Energy (PE)
This is the amount of energy an object has while moving or _______ = 1/2*m*v^2
What is Kinetic Energy
This states that energy cannot be created or destroyed, it can only be transferred or change forms.
What is Energy Conservation
This is the unit that Work is measured in.
What is a Joule (J)/What are Joules (J)
This is the unit that power is measured in _______.
What is Watts
This is the unit that PE is measured in.
What is a Joule/what are Joules
This is the unit that Kinetic Energy is measured in.
What is a Joule/what are joules.
This type of energy increases when there is friction.
What is Thermal/Heat Energy
This is another way to express the unit Joules for work. (Work = Force * Distance, Joules = _______* _______
What is Newton * Meters -- Newton-meter
This happens to power when you increase the amount of work done.
What is increasing your power, increasing the power, increasing power
If you double an objects height, this happens to your Potential Energy.
What is doubling your Potential Energy
If I double an objects velocity, I do this to my kinetic energy.
What is quadruple Kinetic Energy /KE becomes 4 times as big.
An object falls from a height h with 0 air resistance. The object is at one half (1/2) its original height. The potential energy lost is equal to this energy gained.
What is Kinetic Energy gained.
The direction of displacement and the direction of the force applied are in the SAME DIRECTION. This means that work will be a _______ value.
What is a positive value
This happens to power when you increase time.
What is decreasing power, decreasing your power, decreasing the power
Before an object begins to move, the Total Mechanical Energy an object has is equal to its _______.
What is Potential Energy
A pendulum is swinging back and forth. As the pendulum moves from its lowest point to its highest point, its energy transfers from Kinetic Energy to this type of energy.
What is Potential Energy
As I lift an object higher I do work on the object. As I do work on the object, the objects increases this type of energy.
What is Increasing Potential Energy
The direction of the displacement and the direction of the force are PERPENDICULAR TO EACH OTHER. This means that the amount of work done will be ______.
What is 0 Joules
If I do 2000 Joules of work in 5 seconds, I produce this amount of power.
What is 400 watts.
An object moves down a ramp without friction. The object loses potential energy and gains this type of energy.
What is Kinetic Energy.
A hot wheels car is moving down a ramp with friction. The potential energy the car started with is now these types of energy.
What is Kinetic Energy and Thermal/Heat Energy
DAILY DOUBLE EXTENSION PROBLEM!!!!!!!! The equation ∆PE = ∆KE shows how energy may be converted. In the same equation ∆mgh = ∆1/2*m*v^2, this property of the object cancels out in PE and KE.
What is mass. This means that the mass of the object does not matter when finding out how much energy is transferred from PE to KE or KE to PE.
