100
This is the amount of force applied over a certain distance or Blank = Force x distance
What is Work
100

What are mechanical devices that make work easier?

What are Simple Machines

100
This is the amount of stored energy in an object based on it's height or Blank = m * g * h
What is Potential Energy (PE)
100
This is the amount of energy an object has while moving or Blank = 1/2*m*v^2
What is Kinetic Energy
100
This states that energy cannot be created or destroyed, it can only be transferred or change forms.
What is Energy Conservation
200
This is the unit that Work is measured in.
What is a Joule (J)/What are Joules (J)
200

Which Simple Machine reduces friction?

What is a Wheel and Axle

200
This is the unit that PE is measured in.
What is a Joule/what are Joules
200
This is the unit that Kinetic Energy is measured in.
What is a Joule/what are joules.
200
This type of energy increases when there is friction.
What is Thermal/Heat Energy
300
This is another way to express the unit Joules for work. (Work = Force * Distance, Joules = Blank * Blank
What is Newton * Meters -- Newton-meter
300

Which 2 simple machines can reduce the effort it takes to lift objects upwards?

What is an Incline Plane and a Pulley

300
If you double an objects height, this happens to your Potential Energy.
What is doubling your Potential Energy
300
If I double an objects velocity, I do this to my kinetic energy.
What is quadruple Kinetic Energy /KE becomes 4 times as big.
300
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.
400
The direction of displacement and the direction of the force applied are in the SAME DIRECTION. This means that work will be a blank value.
What is a positive value
400

Which simple machine is described as "an inclined plane wrapped around a cylinder"?

What is a screw

400

Before an object begins to move, the Total Mechanical Energy an object has is equal to its blank

What is Potential Energy

400
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
400
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
500
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 blank.
What is 0 Joules
500

What do we call the ratio of output force to input force?

Mechanical Advantage

500

An object moves down a ramp without friction. The object loses potential energy and gains this type of energy.

What is Kinetic Energy.

500
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
500

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.
