Physics 10-4-11 Chair Push

Today in our physics class, we pushed a rolling chair down the hallway. We pushed it with a partner sitting in it. We tried pushing it with fast acceleration and slow acceleration. I learned that I exerted more power trying to use fast acceleration and less when slowly accelerating. Another part of the activity was pushing it when there wasn't any thing in the chair and then when some one plus a weight was in the chair. The force used in pushing something varies inversely to the weight of the thing being pushed, meaning that the heavier the item, the harder it is to push.
