A box rests on a plank that is inclined to the horizontal. As the angle between the plank and the horizontal increases, does the component of the weight of the box parallel to the plank increase, decrease, or remain the same? Explain not sure


The component of weight down the plank is equal to mg*sinTheta. What does sin Theta do as theta increases?


Does sin Theta remain the same as theta increases


If the value of theta changes, then the value of sin(theta) will change (every 2pi radians or 360 degrees).


Yes but does it increase, decrease or remain the same in reference to original question posted


Picture a plank lying flat on the ground. The angle between the grown and the plank is now zero. The question tells you that the plank is inclined with reference to the ground. Do you think the angle is now zero or do you think the angle is greater than zero? What do you think the angle between the plank and the ground is when the plank has been inclined so that the plank is vertical?
