What is Speed?

Speed tells us how fast or slow something moves. It is a way to measure how much distance an object travels in a certain amount of time. The faster something moves, the more distance it covers in less time. The slower it moves, the less distance it covers in the same time.

We can use a simple formula to find speed: Speed = Distance ÷ Time. This means we divide the distance traveled by the time it took. For example, if you walk 2 miles in 1 hour, your speed is 2 miles per hour, or 2 mph. If you run 10 feet in 2 seconds, your speed is 5 feet per second.

Different things move at different speeds. A cheetah is the fastest land animal and can run up to 70 mph! A car on the highway usually goes about 65 mph. A kid running might reach 10 mph. A turtle walks very slowly at 0.2 mph, and a snail moves even slower—only about 0.03 mph.

We measure speed using units like miles per hour (mph) or feet per second. Speed is like asking, “How many steps do you take while your friend counts to ten?”

Speed can change. When you start moving, you might go slow, then speed up, or slow down, and finally stop. Cars have a tool called a speedometer that shows how fast they are going. You can measure your own speed on the playground by timing how long it takes to walk or run across it, and then comparing your speeds.

Knowing speed helps us in races, planning trips, and staying safe. It is a helpful way to understand how objects move in our world.

Interesting Fact: The fastest speed ever recorded for a human is about 27.8 mph, set by sprinter Usain Bolt!
