What is "also increases"  or "goes up"  or "gets stronger" 

400

Force and motion must be applied in the __________________ for work to be done. 

What is the same direction.

400

When you increase the amount of work done, but decrease the amount of time, the amount of Power used will ___________ . 

What is increase.

When you drop the cart from the top of the ramp, are you doing work on the cart? 

What is no, because I am not applying a force (gravity is pulling the cart down).

What does it mean in physics for an object to be "in motion"...no lame answers please

What is "it's distance/position from a reference point is changing"
