Suggested Timeframe Learning Activities to understand how speed and velocity are computed, Il is important to record the time and the distance travelled, Speed Distance Time Let us take a look at the examples below A car is moving at uniform speed of 30 miles north in 0.5 hour. What is the speed of the care Given: distance = 30 miles, lime 0.5 hour, speed= Homiles Speed 60 mph The car's speed is 60mph. Velocity is expressed as 60mph, North Indicating the direction, In some examples, distance or time is not given. In this case, the equation below could help. Be sure to cancel the same unit to get the corresponding unit. Distance Speed X Time Time Acceleration on the other hand, is expressed when speed or direction both change. Speeding up is acceleration and slowing down is deceleration To further enrich your understanding about the lesson, please refer to Science 7 Learner's Material, pp. 175, Activity 3: Fun Walk
