Test Your Understanding of Forces and Friction

AI Thread Summary
The discussion focuses on understanding forces and friction through true or false statements. The first statement addresses the force exerted by the floor while walking, highlighting the role of friction. The second statement examines the relationship between distance and gravitational force, emphasizing that closer proximity increases attraction. The third statement compares static and sliding friction, noting that overcoming static friction is generally more difficult. These concepts are crucial for grasping the principles of physics related to motion and forces.

Homework Statement


1. The force that propels you forward as you walk across the floor is the force that is exerted by the floor itself. T or F

2. If you were sitting half as far from your nearest classmate, the gravitational force of attraction between the two of you would be four times as strong. T or F

3. For any pair of surfaces, the coefficient of static friction between the surfaces is less than the corresponding coefficient of sliding friction. T or F







Homework Equations





The Attempt at a Solution

1. Hint: This depends on friction or frictionless surface.
2. Hint: Gravity acts downward.
3. Hint: It is harder to get past static friction than kinetic or sliding friction.
 

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}...
