Answer:
6. True
7. False
8. True
9. False
10. True
Step-by-step explanation:
The force of gravity acting on an object is measured by weight because weight is also refers to the force having gravity instead of acceleration. In the examples i. e. friction and gravity are types of force but velocity is not a force, it refers to speed of an object. If both forces having same magnitude but opposite in direction then both forces cancel their effect and the object remain stationary. No, length of a force arrow does not represent the direction of the force, it represents magnitude of a force. Yes, force can stop or tend to stop a moving object and move or tend to move a stationary object.
