Acceleration
Acceleration
The rate of change of velocity over time, measured in meters per second squared (m/s²).
Distance traveled at constant speed
Distance traveled at constant speed
The distance traveled by an object at a constant speed, calculated by multiplying the speed by the time taken.
Average speed
Average speed
The average speed of an object over a given distance and time, calculated by dividing the total distance by the total time.

- Find the constant speed of the bus.
- A train travels 16240 meters in 10 minutes 30 seconds.
- Calculate the average speed of the train in km/h.
Question 2
- A speed-time graph shows the journey of a car.
- The car accelerates uniformly at a rate for 15 seconds before reaching a constant speed of 30 m/s.
- Find the acceleration for the first 15 seconds.
- Calculate the time, T, in minutes, when the total distance travelled is 45 km.
Question 3
