Speed, velocity, and acceleration are important ideas when we talk about motion.
Speed is how fast something is going. It's simple because it only tells us the amount. For example, if a car goes 60 km/h, that’s its speed.
Velocity is a bit different. It tells us not only how fast something is moving but also the direction it's going. So, if the same car is moving at 60 km/h to the north, that’s its velocity.
Acceleration is all about how quickly something speeds up or slows down. It shows how velocity changes over time. For example, if a car speeds up from 20 km/h to 60 km/h in 5 seconds, we can find its acceleration using this formula:
This means the car's speed increases by 8 km/h every second.
Knowing these differences can help you understand motion graphs better!
