PHYSICS TEST-6 CL-IX SET-2 F.M=20
Sl No. QUESTIONS Marks
1. Assertion (A): A swimmer pushes water backward to move forward. 1
Reason (R): The backward push on the water creates an equal and opposite
forward reaction force.
2. A body of mass 5kg having a velocity of 80m/s experiences a force in the 2
opposite direction. The body is brought to rest in 8 seconds. Calculate the
retarding force.
3. The diagram shows a moving truck. Forces A, B, 2
C and D are acting on the truck.
Name the type of forces acting on a truck.
4. State Newton’s 2nd law of motion. Derive an expression for it. 3
5. Write 3 differences between mass and weight? 2
6. Fig. 3.1 shows a distance-time graph for a moving object. 3
(a) Describe the speed of the object between points (i) A and B, (ii) B and C
(b) State whether the acceleration of the object is zero, negative or positive, as
shown on the graph between points (i) A and B, (ii) B and C
(c) Calculate the average speed of the object during the 40 seconds.
7. Two bodies P and Q have masses m and 8m respectively. They are moving with 2
velocities 8V and V respectively. Assuming bodies are moving with uniform
velocities,
Compare their:
