A box is pulled a distance d across the floor by a force F which makes an angle 6 with the horizontal (see figure below). If the magnitude of the force were kept constant but the angle 6 were increased, the work done by the force would

a. increase.
b. remain the same.
c. either increase or decrease, depending on the magnitude of the force F.
d. decrease.
e. either increase or decrease, depending on what the initial angle theta was.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
