Class 9 Cbse Physics

CBSE TEST PAPER-03 CLASS - IX Science (Motion) 1. What does the slope of hurrying time interpret give? (a) Distance (c) Acceleration (b) work shift (d) Change in stop number. [1] 2. The displacement of the form can be(a) unconditional (c) Zero (b) negative (d) whole of these. [1] 3. Which of the following gives both direction and magnitude(a) scalar (c) Both (b) vector (d) None. [1] 4. If a moving consistency comes to rest, then its acceleration is(a) Positive (c) Zero (b) negative (d) All of these depending upon initial velocity. [1] 5. A automobile trunk is moving with a velocity of 12m/s and it comes to rest in 18m, what was the acceleration? [2] 6. A body starts from rest and moves with a uniform acceleration of 4m/s2 until it travels a break throughstrip of 800m, find the find velocity? [2] 7. The driver of a railroad car traveling along a straight road with a zip up of 72KM ph observes a signboard which give the speed limit to be 54KM ph. The signboard is 70m ahead when the driver applies the brakes0 seem the acceleration of the car which will cause the car to stretch the signboard at the stated speed limit? [2] 8. 9. fork between scalars and vectors?

The displacement x of a particle in meters along the x- axis with time t in seconds harmonise to the equationX= 20m +( 12m )t s [2] [3] (a) draw a interpret if x versus t for t = 0 and t =5 sec Material downloaded from hypertext transfer protocol://myCBSEguide.com and http://onlineteachers.co.in Portal for CBSE Notes, Test Papers, Sample Papers, Tips and Tricks (b) What is the displacement come out of the particles initially? (c) What is slope of the graph obtained? 10. The velocity of a body in motion is recorded every second as shown[3] calculate the (a) Acceleration (b) distance travelled and draw the graph. 11. pose the graph for uniform retardation (a) position time graph (b) velocity time (c) Acceleration- time 12. The displacement time graph for a body is given. State... If you want to get a salutary essay, order it on our website: Orderessay
