Wow. What's really sad is that I was thinking about how they were symmetrical, but I never bothered to actually split it in half and solve it that way. Thanks a lot, Ken G!

I'm having trouble working with the equations I've found because I don't know the initial and final velocities (after being thrown upward and before being caught) or the distance. I have: V_{}f = V_{}i + a*t V_{}f2 = V_{}i2 + 2*a*d d = V_{}i*t + \frac12{}{}*a*t2 d = ((V_{}i + V_{}f)...

Supposing an object is thrown into the air and the only relative data you know is the amount of time it was in the air, the mass of the object, and the acceleration due to gravity being -9.8 m/s^2, can you figure out the distance it traveled and the velocity it had when it landed? And how...

So would it be bad to assume that the person would stop instantaneously? I would think that would be incredibly difficult to happen in real life.

I'm quite confused about impact force and weight, as well as momentum. Assuming someone were to fall from a 5-story building, about 20 m, how would you calculate the force upon impact? I know it involves momentum, but I can't quite grasp it. Also, if someone fell from the building, but instead...

But isn't the centripetal force going inward? I want to know how you figure out how much force is pushing you outwards. Not that it actually is, since centrifugal force isn't an actual force. But there must be a way to determine how much outward motion would be experienced by someone moving at a...

So, G-Force is the same as centripetal acceleration?

Oh, it's angular velocity. If someone is riding on a merry-go-round, or teacups, or something similar, they move outwards, due to "centrifugal force". Is there a way to calculate how much of that force is being applied to them as they are pushed against a wall or something similar? And how fast...

How do you calculate G-Force? I know that one g is the force gravity exerts on a particular mass (I think). But how exactly do you figure it out, particularly with objects spinning in a circle, like a merry-go-round?

So if you knew the centripetal force and acceleration, along with the radius and tangential velocity, how would you calculate the effects of centrifugal force? If the someone were spinning around something at a certain speed, how fast would they be moving outwards?

I'm confused. How does centrifugal force factor into uniform circular motion? Is it equal but opposite centripetal? If someone is spinning so that there are 20 N of centripetal force, does that mean there are -20 N of centrifugal force?

Thank you for the clarification. Would you mind explaining how it works for me, though? For example, if someone is in a ride spinning at a certain speed, how fast would they be moving outwards? EDIT: Would centrifugal force effectively be an opposition to centripetal force, balancing out the...

I'm in my first year of physics and I'm having trouble understanding some aspects of centripetal force. When someone is spinning rapidly on, say, an amusement park ride, they tend to be pushed outward the faster they go. Is this the tangential velocity? Or does it involve a different aspect of...
