Question 1: What is the velocity of the object at time t = 4 seconds according to the graph? Show your working.

Answer: Use the graph to read the velocity at t=4 seconds

Question 2: Calculate the total displacement of the object between t = 0 and t = 8 seconds.

Answer: Area under the graph between t=0 and t=8 seconds

Question 3: Describe the object's motion during the first 3 seconds based on the graph.

Answer: Object is moving at a constant velocity or changing velocity as observed

Question 4: Plot the graph of y = 2x for x from 0 to 5. Use the grid to draw the line.

Answer: Draw a straight line passing through (0,0) and (5,10)

Question 5: Construct a velocity-time graph where the object accelerates uniformly from 0 to 10 m/s over 5 seconds, then moves at constant velocity. Show your construction on the grid.

Answer: A rising line from (0,0) to (5,10) followed by a horizontal line from (5,10) onward

Question 6: The graph shows a period where the area under the line is negative. What does this indicate about the object's motion?

Answer: Object is moving in the opposite direction or returning towards the starting point

Question 7: Identify the interval during which the object was at rest (velocity = 0).

Answer: Read from the graph where the line is on the x-axis

Question 8: A student misreads a graph and states that the object’s velocity is constant at 4 m/s throughout. Based on the graph, identify and explain the mistake.

Answer: The graph shows changing velocity, not constant; identify where the slope varies

Question 9: A car accelerates from 0 to 20 m/s over 10 seconds, then maintains this velocity. Draw and interpret the graph representing this motion.

Answer: A straight line from (0,0) to (10,20), then horizontal from (10,20) onward

Question 10: Determine the average velocity of the object over the entire 12 seconds shown in the graph.

Answer: Total displacement divided by total time
