Questions & Answers

Q: How can the displacement of a particle be calculated using a velocity-time graph?

The displacement is obtained by finding the area under the curve of the velocity-time graph. By breaking the graph into rectangles and triangles and calculating their areas, the total displacement can be determined.

Q: Why is the area of rectangles and triangles on the velocity-time graph used to calculate displacement?

The area under the curve represents the change in position or displacement. By dividing the graph into simple geometric shapes, the calculation becomes easier and the total displacement can be accurately determined.

Q: Is displacement a vector quantity?

Yes, displacement is a vector quantity, meaning it has magnitude and direction. The direction can be positive or negative, depending on the direction of motion.
