Calculating Kinetic Energy without Time: Is it Possible?

AI Thread Summary
Total Kinetic Energy (KE) can be calculated using the formula KE = 0.5mv^2, where 'm' is mass and 'v' is velocity. Time is not directly needed to calculate KE, but velocity must be known or derived from other information. Without velocity, it is impossible to determine KE accurately. Therefore, while time itself is not required, understanding how to obtain velocity is essential for the calculation. Accurate calculations of kinetic energy hinge on knowing the object's velocity.

1. Is it possible to work out Total Kinetic Energy without a Time figure



2. KE=0.5mv^2



3. Do I therefore need time to calculate V?

Yes, you need the velocity in order to calculate an object's KE. Welcome to the PF.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
