Week 2

You accelerate for many reasons when you are riding a bike. For instance, if you were about to ride your bike up a steep hill you would have to accelerate by pedaling faster to make it to the top. Another reason you would need to accelerate is if you were riding your bike at the strand along the beach. Usually, there are many people riding on the strand you need to accelerate if there are people behind you trying to get by to get out of their way. If you were in a bike race you would need to accelerate to pass up the person in front of you and win the race.

2. What is initial velocity?
 3. What is the general meaning of acceleration?

Week 1

Softball is a sport that includes many of the definitions we use in physics. In softball one of the things you use often is speed. You need speed to run the bases, throwing the ball and fielding.  The more speed you have the better chance to have being safe at base and getting the opponents out faster. For a pitcher, the more speed you have coming off the mound the better of a pitcher you are, and the harder it is for the batter to get a hit. We use distance to know how far we need to stand in the outfield or when we chalk the field to prepare for a game. We measure the distances from base to base, making it more accurate. In some games, the scoreboard is used to set a time limit for how long we can play a game. Having the time helps the players know that if they are down runs in a game, they have as certain amount of time to get ahead.

2. A change in position is also known as?
