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.
Acceleration is a speeding up, slowing down or a change in direction. Is the following acceleration and if so, which one?
A dancer is warming up. She turns on music with a good beat and does 10 pirouettes in a row perfectly on the beat. (pirouette is a body spin in ballet)
Yes, this is acceleration since the dancers is going a certain speed.
Yes, this is acceleration since the dancer is changing direction when she spins.
No, this is not acceleration since there is no speeding up, slowing down, or change in direction.
This occurs when an object speeds up, slows down, or changes direction.
