What does speed up mean?

Speed up means going faster, just like when you pedal harder on your bike and zoom past your friend.

Think about riding your bike down a hill. At first, you're going slow, maybe even pushing with both feet. But then you start to pedal harder, and whoosh, you’re flying! That’s what speeding up feels like: you’re moving more quickly than before.

Now imagine a race car at the start of a track. It's just sitting there, not moving. Then the driver hits the gas, and vroom, it zooms off! The car is speeding up, just like you on your bike.

It’s like when you run from one end of the playground to the other. At first, you're walking, but then you start running, and you get there quicker. That’s speeding up, going from slow to fast! Speed up means going faster, just like when you pedal harder on your bike and zoom past your friend.
