What is the difference between distance and the displacement? [2] What is a uniform motion and a non-uniform motion? [2] Usha swims in a 90 m long pool. She covers 180 m in one minute [3] by swimming from one end to the other and back along the same straight path. Find the average speed and average velocity of Usha. Ashok travels first 60 km with the speed of 30 km / hour and the [3] next 60 km with the speed of 60 km / hour. What is his average speed in km / hour and in m / s? Mahesh travels the distance from the home to the school at the rate of [4] 60 km / hr and back from school to the home at the rate of 30 km / hr. What is the average speed of the Mahesh? What is uniform acceleration? [2] Show with the help of the figure the nature of the curve of the object [3] moving with uniform sped and non-uniform speed with the help of distance time plotted on ordinate and abscissa. Show with the help of the velocity time graph the nature of the curve [2] for uniform motion of a car. Derive the equation v = u + at. [4] 2 The brakes applied to a car produce an acceleration of 6 m/s in [3] the opposite direction to the motion. If the car takes 2 s to stop after the application of brakes, calculate the distance it travels during this time. A driver of a car traveling at 52 km h-1 applies the brakes and [4] accelerates uniformly in the opposite direction. The car stops in 5 s. Another driver going at 3 km hr1 in another car applier his brakes slowly and stops in 10 s. On the same graph paper plot the speed versus time graphs for the two cars. Which of the two cars traveled farther after the brakes were applied? An artificial satellite is moving in a circular orbit of radius [3] 42250 km. Calculate its speed if it takes 24 hours to revolve around the earth. Answer in brief [5] (1)
What is the unit of speed in SI unit system?
(2) (3) (4) (5)
What is the formula of the average speed? What does the odometer of an automobile measure? Can an object have zero displacement but non zero distance? How? The displacement of the object can be greater than the distance traveled by an object? True or false
