Speed is how fast something moves. It's measured in units like miles per hour (mph), kilometers per hour (km/h), or meters per second (m/s).
Average speed is the total distance traveled divided by the total time taken. For example, if you drive 100 miles in 2 hours, your average speed is 50 mph.
Instantaneous speed is the speed at a specific moment. For example, your car's speedometer shows your instantaneous speed.
Velocity is speed with a direction. For example, driving north at 60 mph is a velocity.
Acceleration is how fast the speed changes. For example, a car speeding up is accelerating.
