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

1. Define: What is the difference between a scalar and a vector quantity?

2. List: Give two examples of scalars and two examples of vectors.

3. Define: What is acceleration? What is its standard unit?

4. Identify: What does the gradient (slope) of a displacement-time graph represent?

5. Identify: What does the area under a velocity-time graph represent?

6. State the formula: Write down the equation for calculating acceleration.

7. Define: What is displacement?

8. Recall: What is the unit for velocity?

9. Identify: What type of motion is represented by a horizontal line on a velocity-time graph?

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

1. Compare: A car travels 400 m on a circular track and returns to its starting point. What is the distance it travelled? What is its displacement? Explain your answers.

2. Explain: Describe how you would calculate the velocity of an object from its displacement-time graph.

3. Describe: A car is slowing down. Is its acceleration positive or negative? What is another term for this?

4. Apply: A train journey is shown on a velocity-time graph. How would you calculate the total distance the train travelled?

5. Explain: Explain the difference between average speed and instantaneous speed.

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

1. Graph Analysis: You are given a velocity-time graph of a moving object. The graph starts at the origin, slopes up in a straight line to a velocity of 20 m/s at 10 seconds, then continues as a horizontal line for 5 seconds, and finally slopes down in a straight line to 0 m/s at 20 seconds. (a) Describe the motion of the object in the first 10 seconds. (b) Calculate the acceleration of the object between 0 s and 10 s. (c) What is the total displacement of the object during the 20-second journey? Show your calculations.
