As the car travels through town, it would leave a trace of oil on the street that would reveal information about the motion of the car. The trace of the oil in four different situations are shown. (The positions are given in centimeters.) 1. Identify the type of motion by the car in situations A, B, C and D. __________________________________________________________________________ __________________________________________________________________________ 2. What is the ratio of speed of the car in situations A, B and C? (a) 1:2:4 (b) 2:1:4 (c) 4:2:1 (d) 2:4:1 3. What is the acceleration of the car in situation D? __________________________________________________________________________ __________________________________________________________________________ 4. In case D, if the oil drop diagram shows the motion of a left-ward-moving object, Which force diagram(s) is/are consistent with the oil drop diagram? (The arrows represent forces; arrow length represents the size of the force.) (a) A only (b) B only (c) B and C (d) D and E 5. Statement 1: A positive acceleration of a body can be associated with ‘slowing down’ of the body. Statement 2: Acceleration acts along the direction of velocity of the body. Choose the correct option: (a) Both Statement 1 and Statement 2 are true. (b) Both Statement 1 and Statement 2 are true and Statement 2 is the correct explanation of Statement 1. (c) Statement 1 is true but Statement 2 is false. (d) Statement 1 is false but Statement 1 is true. (e) Both Statement 1 and Statement 2 are false. 6. Draw the oil drop diagram of a car moving to the right and slowing down and a car moving to the left and speeding up. What is the difference between the two? __________________________________________________________________________ ___________________________________​
