Acyclist is riding his bike at a constant speed of s m/s, and experiences a frictional force between the bike and sidewalk of 100 n. the cyclist then changes his speed to 10 m/s what effect does this increase in speed have on the frictional force between the bike and sidewalk?
a) the frictional force doubles because when speed increases frictional force also increases
b) the frictional force becomes half of what it was because when speed increases frictional force decreases
c) the frictional force increases but does not double because although friction increases with the increasing speed it does not increase as fast
d) the frictional force between the bike and sidewalk stays the same because speed does not affect frictional force

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.
