Calculating Velocity
Learning Objective
I can calculate the velocity of an object using distance and time.
Key Concepts
Speed is the distance an object travels per unit of time, while velocity is speed with a direction.
The formula for speed is speed equals distance divided by time.
If a student runs 250 meters in 30 seconds, their speed is 8.33 meters per second. A car that traveled 75 kilometers North in 1.5 hours has a velocity of 50 kilometers per hour North.
