Question
How can you calculate the acceleration from a velocity-time graph?
Answer
To calculate acceleration from a velocity-time graph, you need to determine the gradient of the line. The formula for acceleration is given by the change in velocity divided by the time taken.
Explanation
This question evaluates the student's ability to apply mathematical skills to analyze a graph. It requires understanding the relationship between the gradient of a graph and the concept of acceleration, reinforcing the connection between graphical data and physical quantities.
Common mistake
Misunderstanding Velocity-Time Graphs
Students often confuse the interpretation of the gradient of a velocity-time graph, thinking it represents distance rather than acceleration.
Remember that the gradient of a velocity-time graph indicates acceleration, while the area under the graph represents distance travelled.
