Question
-What does the coefficient of friction represent?
the amount of inertia that must be overcome
the amount of force needed to change motion
the amount of stickiness two substances share
Use this diagram to answer the next two questions.
-Which diagram below matches the system schema shown?
-You push a rolling chair across a smooth tile floor by giving it a shove. The chair shoots across the room while you remain in place. Which statement describes the appearance of the system schema?
No line connects your hand to the chair because you are no longer in contact with it and do not influence the motion.
A dotted line connects your hand to the chair because you are no longer in contact with it, but your push caused the motion.
A solid line connects your hand to the chair because even though you are no longer in contact with it, your push caused the motion.
-Which force or which component of a force balances the friction force in the diagram shown?
the component of gravity force that is perpendicular to the ramp
the support force
the component of gravity force that is parallel to the ramp
-What is the value of the tension force in the rope? The mass of the bucket and its contents is 6.2 kg. The acceleration is 0.93 m/s^2 upwards.
66.6 N
5.77 N
55.1 N
-By referring to the nine similar diagrams in the text discussion and examples, for the system schema shown, how many forces will be placed on the indicated object when the force diagram is drawn?

Explanation / Answer
qns 1 )
the amount of stickiness two substances share
qns 2 ) B option
qns 3 )
A solid line connects your hand to the chair because even though you are no longer in contact with it, your push caused the motion.
qns 4 )
the component of gravity force that is parallel to the ramp
qns 5 )
mg-T = ma
T = m(g-a)
T = 6.2 ( 9.81-0.92)
T = 55.2 N
qns 6 )
3
friction ,gravity and tension
