Question

draw a velocity time graph for the following data and find the displacement at the end of 5sec from the graph
time in sec 0 1 2 3 4 5
velocity in sec 0 7.5 15 22.5 30 37.5

Answer 1

Answer:

velocity it is the distance travelled by a body per unit time in a given direction it is a vector quantity its SI unit is metre per second it can be positive negative or zero depending on situation velocity is equal to displacement. Time short form V is equal to S appointee average velocity Total distance covered total time taken in case that the velocity is changing at a uniform rate uniform velocity of body has uniform velocity if it travels in a straight line covering equal distances in equal intervals of time no matter how small these intervals maybe non uniform velocity of a body has non uniform velocity if it covers an equal distances in equal intervals of time in a straight line or it cause equal distances in unequal intervals of time in a straight line or it covers and distances in equal intervals of time the change in direction of motion or its covers an equal distance in equal intervals of time in the change in direction of motion this is known as non uniform velocity
