What do you already know about speed and velocity?
Learning Objective
At the end of the lesson you will be able to explain the relationship between speed, distance, time, and velocity, and solve basic problems using their formulas.
What is Speed?
Speed is how fast an object is moving. It is calculated as the distance travelled divided by the time taken.
Measuring Time
Time is the duration taken to cover a distance. Common units are seconds, minutes, and hours.
The Speed Formula
Speed = Distance ÷ Time
Formula
Example
If a car travels 100 km in 2 hours: Speed = 100 km ÷ 2 h = 50 km/h.
What is Velocity?
Velocity is speed in a given direction. Unlike speed, it tells us both how fast and in which direction an object moves.
Applying What You Learned
Try calculating the speed and velocity of an object given distance, time, and direction. Reflect on the importance of direction in real-life scenarios, such as navigation or sports.

Understanding Distance
Distance is the length of the path travelled by an object. It is measured in units like metres or kilometres.
