Velocity

Velocity is how fast something is moving and the direction it's going. For example, if a car is going 60 miles per hour to the north, that speed and direction together make up its velocity.

Examples

• The velocity of a soccer ball can change quickly when a player kicks it, making it fly in different directions during the game.
• In science class, we learned that the velocity of a roller coaster affects how thrilling the ride is, especially when it zooms down steep hills.
• When I ride my bike down a hill, the velocity increases so fast that I can feel the wind rushing past me and it makes me giggle with excitement.
