Acceleration is a speeding up, slowing down or a change in direction. Is the following acceleration and if so, which one?
A swimmer has 10 meters left in the race and he is neck-in-neck with his competitor. He has a surge of adrenaline and pulls ahead to win.
Yes, this is acceleration since the swimmer starts to speed up to pull ahead.
Yes, this is acceleration since the swimmer uses the wall to change directions.
No, this is not acceleration since there is no speeding up, slowing down, or change in direction.
True or False: You are standing at the bus stop and not moving at all. Since you are not moving, your acceleration would be 0 (zero). Support with how you know.
True since you are not speeding up, slowing down or changing directions.
True since you are traveling no distance in a certain amount of time.
False since you are speeding up, slowing down and/or changing directions.
False since you were going to get on a moving bus.
