AI Thread Summary
The work done by gravity on a horizontally moving load is zero because the gravitational force acts vertically while the movement occurs horizontally. Since work is calculated as the force component in the direction of movement multiplied by the distance moved, and there is no movement in the vertical direction, the work done is zero. This conclusion is supported by the understanding that only forces acting in the direction of motion contribute to work. Thus, in this scenario, gravity does not perform any work on the load. The discussion emphasizes the relationship between force direction and work calculation.

A man pushes a heavy load across a horizontal floor. What is the work done by gravity on the load?
a. The work depends on the weight of the load.
b. The work done by gravity is negative.
c. The work done by gravity is zero.
d. The work done by gravity is positive.

the load is moving horizontally where as the gravitational force is vertical so i think its zero??

Why is it 0? I gave you a clue on the other thread you started.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
