1. Two students push a box in the same direction with forces of 10 N and 6 N. The total force is:
A. 4 N
B. 16 N
C. 60 N
2. A box is pushed with 12 N to the right and 7 N to the left. The net force is:
A. 19 N to the left
B. 5 N to the left
C. 5 N to the right
3. A box is pulled with 8 N from the left side and 8 N from the right side. The forces are:
A. Balanced
B. Unbalanced
C. Magnetic only
4. A ball rolling slowly is pushed again in the same direction. What will most likely happen?
A. It will stop immediately
B. It will move faster
C. It will lose its mass
5. A moving marble is gently hit from the side. The marble will most likely:
A. Become invisible
B. Change into a gas
C. Change its direction
6. A cricket bat hits a fast ball and sends it back in another direction. This shows force can change:
A. Speed and direction
B. Colour and smell
C. Mass and volume only
7. If the same toy car is pushed gently first and then pushed harder, the harder push will usually make it:
A. Move slower always
B. Move faster
C. Stop being matter
8. Tyres need friction with the road mainly to:
A. Remove gravity
B. Make the road disappear
C. Get grip on the road
9. Tyres have grooves or treads to:
A. Increase grip
B. Make friction zero
C. Reduce the weight of Earth
10. Ball bearings are used in machines mainly to:
A. Increase heat always
B. Reduce friction
C. Remove all force
11. When we rub our palms together quickly, they become warm because friction produces:
A. Ice
B. Magnetism only
C. Heat
12. Shoe soles become thinner after long use mainly because of:
A. Friction
B. Reflection
C. Evaporation
13. A ball thrown upward comes back down because of:
A. Muscular force of the hand after release
B. Gravitational force
C. Friction in shoes only
14. If a heavier object is hung from a spring balance, the spring will:
A. Become shorter always
B. Show no reading
C. Stretch more
15. A charged balloon sticks to a wall without being held. This is due to:
A. Electrostatic force
B. Muscular force
C. Force of boiling
16. A book resting on a table does not fall through the table because the table exerts:
A. Magnetic force only
B. Contact force upward
C. Heat force downward
17. If a box is sliding to the right on the floor, friction acts:
A. Upward only
B. To the right
C. To the left
18. A cart is pulled with 15 N east and 10 N west. It will tend to move:
A. East
B. West
C. Nowhere because both forces are equal
19. When a spring is pulled, it becomes longer. This shows force can:
A. Destroy time
B. Change shape
C. Remove volume completely
20. A paper boat moves when flowing water pushes it. This shows that flowing water can:
A. Change into fire
B. Have no effect on objects
C. Exert force
