1) What effect is caused on an elastic band by the force applied on it? a) The elastic band shortens and thickens. b) The elastic band elongates and becomes narrower. c) The elastic band expands. d) The elastic band becomes broader. 2) The effects produced by a force on two cars that experiences a head - on - collision.  a) speed increases b) length of bodies increase c) direction of motion change d) shape and size change and motion stops 3) A car that was headed North wards soon heads in the north - east direction with constant velocity. What observable effect does the force produce on the moving car? a) Change in direction. b) Increase in speed. c) Comes to rest. d) Change in size. 4) The effect of force produced on a tin that is crushed using a heavy duty hammer corresponds to. a) Its length increases. b) It begins to move. c) Its size becomes smaller and shape is wrinkled. d) Its size increases. 5) Identify the effect of a force produced when a car just accelerates from rest. a) Change in state of motion. b) Change in direction. c) Change in size. d) Change in shape. 6) How does the effect of a force applied in stone crushing produce results? a) It produces larger stones of one shape. b) It helps in loading stone in trucks. c) It produces smaller stones of varying shapes d) It carries stone over the conveyor. 7) Identify the effect of force produced in a uniformly accelerated motion of the bus. a) Slows down motion. b) Speeds up motion. c) Changes the direction of motion. d) Stops motion. 8) What causes the speed of a jet to increase in a uniform fluid? a) Reduced air resistance. b) Reduced drag force. c) Increased lift force. d) Increased engine force. 9) Why would a force applied produce no effects on the body's state of motion? a) Because the body is more massive. b) Because the passage is rough. c) Because the body is resistant to any change in motion. d) Because the amount of force applied may be insufficient to produce the effects. 10) The effect of 6 equal forces action on a body is to produce.... a) change in shape and size. b) an acceleration. c) change in direction. d) change in speed.
