Work
This is defined as product of force on an object and the distance moved in the direction of the force or ____ = Force x distance (in the direction of the force).
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 position/ height or _____= mgh
What is Potential Energy (PE)?
This is the amount of energy an object has subject to its motion 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 the law of conservation of energy?
This is the SI unit that Work is measured in.
What is a Joule (J)?
This is the SI unit that power is measured in blank.
What is the Watt (W)?
This is the unit that potential energy is measured in.
What is a Joule?
This is the unit that Kinetic Energy is measured in.
What is a Joule?
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. (Hint: Work = Force X Distance, Joule = _____ X ____.
What is the Newton Meter?
This happens to power when you increase the amount of work done.
What 'increases'?
If you double an objects height, this happens to your Potential Energy.
What 'doubles'?
If I double an objects velocity, I do this to my kinetic energy.
What 'quadruples'?
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 'decreases'?
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, at constant speed, I do work on the object. As I do work on the object, the object increases this type of energy.
What increases 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 1/12 minutes, I produce this amount of power in Watts.
What is 400 watts?
An object moves down a ramp at constant speed. The object loses potential energy and gains this type of energy.
What is internal/ heat/ thermal 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 Internal/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.
