Consider a sping of length, L m and spring constant K N/m. If a force of F N is applied, we will expect the spring to be extended by x m. So The variables(F,K,x) can be combined to formed an equation, known as the hookes law i.e F=Kx. Does the length of spring have any effect on the extension...

it really helps me. thanks a lot for the reply. =)

Imagine u have a ball on top of an inclined plane. The ball is released, hence initial velocity is zero. Assume that air resistance and friction between the surface and ball is negligible. using kinematic equations, V2=2as, where a=gsinθ, θ is the angle of inclination of the plane and s is the...

thx uart... =)

oooo..i have forgotten the downthrust thx to all that have help me... i understand now..

I can only think of the weight of the beaker of water... so do u mean that the balance's reading is the same regardless of whether the suspended ball is present, since the force have come to equilibrium?

dang..sry abt that...is it possible to show me the equations? equations tell the whole story =D..thanks

there is upthrust. So do u mean the there is a equal but opposite force which is equal to the magnitude of upthrust acting on the ball? if it is so wouldn't the tension equals to the weight of the ball ie. T=mg?

oh man i still don't understand...

Homework Statement An iron ball is suspended in the air by a string attached to the ceiling. This iron ball is then submerged into the a beaker of water on top of a measuring balance, such that the ball is not in contact with the base of the beaker. When the beaker of water(without anything in...

Thanks uart for your explanation about projectile motion. But i wasn't referring to projectile motion. I was referring throwing a ball being thrown up in the air, in which its path up to its maximum height and return journey is always perpendicular to the ground at all time. Can anyone help to...

Air resistance will reduce the time needed to reach maximum height and increase the time needed to return from maximum height to original position. I just want to know whether if the reduce the in time needed to reach maximum height will be compensated by the increase the time needed to return...

I have a question to ask. Imagine a ball being thrown upwards with a certain initial velocity. Neglecting air resistance, let the total time for the ball to reach its maximum height and back to its original position be T. With the presence of air resistance, will the total time be any different...

Thx a lot Naty1 for yr help I have gotten a clearer picture now

Hi guys, I got a question that has been in my head for a while. Is the Newtonian gravitational force equivalent to the "tension" in the space time fabric caused by the depression of 2 masses? If it is equivalent, does it means that gravitational force does not act in a straight line but it...
