A car is traveling 20 kilometers an hour. It turns slightly to the left at 20 kilometers per hour. The action that the car takes changes its —

• acceleration, but not its velocity.

• velocity, but not its speed.

• speed, but not its acceleration.

• speed, but not its velocity.

Match the following

• Speed

• A city bus speeds up to make it on time.

• Velocity

• A city bus travels 30km/min to the eastside of town.

• Acceleration

• A city bus travels distance of 10 km in 30 minutes.
