B1 Measurement and representation of motion: Pearson BTEC National Applied Science (AAQ) Questions

Practise b1 measurement and representation of motion with Pearson BTEC National Applied Science (AAQ) questions and mark schemes. Revise B1.1 Standard SI units, B1.1.1 standard SI units and symbols for initial velocity (u), final velocity (v), distance and displacement (s), time (t), and acceleration (a), B1.1.2 units of speed: kilometres per second (kms-1), kilometres per hour (kmh-1).

The topics below follow the course specification. Question availability depends on the papers uploaded; use the question bank filters to see current coverage.

What to revise

• B1.1 Standard SI units
• B1.1.1 standard SI units and symbols for initial velocity (u), final velocity (v), distance and displacement (s), time (t), and acceleration (a)
• B1.1.2 units of speed: kilometres per second (kms-1), kilometres per hour (kmh-1)
• B1.2 Calculating speed and average speed
• B1.2.1 speed = distance ÷ time
• B1.2.2 average speed = total distance ÷ total time
• B1.3 Using vector and scalar quantities to describe motion
• B1.3.1 using velocity as a vector quantity that has magnitude and direction
• B1.3.2 using distance as a scalar quantity that has magnitude only
• B1.3.3 using displacement/time graphs to find velocity
• B1.3.4 using velocity time graphs to describe the motion of an object
• B1.3.5 using velocity/time graphs to find the distance travelled from the area beneath the graph
• B1.3.6 using velocity/time graphs to find acceleration as rate of change of velocity from the gradient of the graph, 𝑎𝑎 = (𝑣𝑣−𝑢𝑢) 𝑡𝑡
• B1.3.7 find the acceleration of a trolley moving down a gradient
• B1.3.8 use equations for the calculation of motion: 𝑠𝑠 = (𝑢𝑢 + 𝑣𝑣)𝑡𝑡 𝑣𝑣 = 𝑢𝑢 + 𝑎𝑎𝑎𝑎 𝑠𝑠 = 𝑢𝑢𝑢𝑢 + 2 𝑎𝑎𝑡𝑡2 𝑣𝑣2 = 𝑢𝑢2 + 2𝑎𝑎𝑎𝑎
• B1.4 Understand the applications of accelerometers, to include: ‘fitbits’, mobile phones and blood pressure monitors

Use questions to check your understanding

Try a question before opening its mark scheme. Show each step in calculations and check the units, significant figures and scientific terms used in your answer. Compare your response with the marking points to see where you can improve.

In the question bank, filter by year and paper, open the original paper, or use split view to compare a question with its mark scheme. The Write tab lets you work on the question and save writing on this device. Add questions to a custom paper for a focused revision session.
