OR

What is Power and time?

100

What two variables would you need in order to calculate power?

What is work and time?

100

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

What is Kinetic Energy (KE)

100

The two variables you need in order to calculate Kinetic Energy.

What is mass and velocity?

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
This is the unit that power is measured in blank.

DAILY DOUBLE PROBLEM!!!!!!! 

This type of energy increases when there is friction.

What is Thermal/Heat Energy

300

DAILY DOUBLE PROBLEM!!!!!!! 

The work done by a 60-watt light bulb lighting a hallway for 2 minutes.

What is 7,200 joules? or What is 7.2 kJ?

300
This happens to power when you increase the amount of work done.
What is increasing your power, increasing the power, increasing power
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

A runner exerts a force of 334 N against the ground while using 2100 watts of power.  The time it takes the runner to run a distance of 50.0 meters.

What is 7.95 seconds?

400

A block that weighs 25 kg is lifted a distance of 20 m, straight up by a rope.  The job is done in 10 s.  What power is exerted by raising the box?

What is 490 watts?

400
Before an object begins to move, the Total Mechanical Energy an object has is equal to its blank
What is Potential Energy
400

Calculate the kinetic energy of a 4 kg rock rolling 15 m/s.

What is 450 joules?

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

If I do 2.5 kilojoules of work in 3 minutes, I produce this amount of power.

What is 13.89 watts?

DAILY DOUBLE PROBLEM!!!!!!! 

A Hotwheels car is moving down a ramp. Calculate the kinetic energy of a 55 gram toy car moving with a velocity of 2.6 m/s. 

What is 0.1859 joules?

500

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.
