AI Thread Summary
Acceleration affects an object's motion significantly based on its direction relative to the object's velocity. When acceleration is in the same direction as the motion, the object speeds up. Conversely, if acceleration opposes the motion, the object slows down. The key quantity associated with the direction of motion is velocity. Understanding these dynamics is crucial for analyzing object motion in physics.

If the direction of the acceleration of an object is the same as the direction of motion of the object, what is the objects motion like?

If the direction of the acceleration of a object is opposite to the direction of motion of the object. what does this mean
 
Physics news on Phys.org
yes i read the replies
 
What quantity is associated with the "direction of motion" of the object?
 
ummmmmmmmmmm velocity
 
first one, its speeding up, second its slowing down
 
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}...
