The area under a velocity-time graph between two instants represents:
Displacement
On a velocity-time graph, the area enclosed between the curve and the time axis over an interval equals the integral of velocity with respect to time, which gives the displacement of the body during that interval. This is a standard result used to relate v-t graphs to motion analysis.
A body moves along a straight line with displacement \(s = 4t^2 + 2ts =4t^2+2ts=4t^2+2t\) (in m, t in s). Its instantaneous acceleration is:
Ram records the odometer readings of his car for the distance covered from 2000 km at the start of his journey and 2400 km at the end of the journey after 8 hours. What is the average speed of the car?
A body moves along a straight line with displacement \(s = 4t^2 + 2ts =4t^2+2ts=4t^2+2t\) (in m, t in s). Its instantaneous acceleration is:
A body is dropped freely from a height 'X' m. If tit takes Y seconds to reach the ground. The time it takes to reach half of the height of the tower is (Take g = 10m/s2)
Which of the following describes the rate at which an object changes its velocity?
