AI Thread Summary
An acceleration versus time graph reveals the jerk, which is the rate of change of acceleration. If the position versus time graph indicates velocity, and the velocity versus time graph indicates acceleration, then variations in acceleration suggest that the net force acting on the object is not constant. Factors affecting acceleration include changes in net force, which can result from various influences. Understanding these relationships is crucial in physics, particularly when applying Newton's laws. Proper formatting and adherence to guidelines are also emphasized for clarity in discussions.

If the position versus time graph describes velocity and if the velocity versus time graph tells acceleration..
In acceleration versus time graph, it describes a jerk(rate of change in acceleration)..



Do you have any idea why acceleration is not constant?
Are there any factors involved?

It just means that the net force is not constant. Something happens that changes the net force

In future, please use the homework posting template provided when you begin a new thread in the homework section of Physics Forums. This is a requirement.

What basic formula do you know that involves acceleration? (hint: think of Newton!).
 

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}...
