Level 1: Core concepts Check (Aiming for a Pass - 'S')

1. State the Formula: Write the formula connecting Speed, Distance, and Time.

2. Convert: Convert a speed of 36 km/h into m/s.

3. Define: What does the gradient of a distance-time graph represent?

4. Calculate: A tank of 1000 litres is filled in 50 minutes. What is the rate of flow in litres per minute?

5. Identify: A distance-time graph shows a horizontal line. What does this indicate about the object's motion?

Level 2: Connecting the Dots (Aiming for a Credit - 'C'/'B')

1. Explain: A train of length 60 m is travelling at 72 km/h. It needs to cross a bridge of length 100 m. Explain the total distance the front of the train must travel to completely cross the bridge.

2. Apply: Using the information from Q1, calculate the time it takes for the train to cross the bridge.

3. Problem-Solve: A bus travels for 15 minutes at 40 km/h and then for 30 minutes at 70 km/h. Calculate the average speed of the bus for the entire journey.

Level 3: Exam Challenge (Aiming for a Distinction - 'A')

Scenario Analysis: A train leaves station A at 08:00 h and travels towards station B, 100 km away, at a uniform speed of 60 km/h. Another train leaves station B at the same time and travels towards station A at a uniform speed of 40 km/h. (a) What is the relative speed at which the two trains are approaching each other? (b) Calculate the time it will take for them to meet. (c) At what time will the two trains pass each other?
