AI Thread Summary
The potential energy (PE) of a 1000 kg car lifted to a height of 1 meter can be calculated using the formula PE = mgh. In this case, m is the mass (1000 kg), g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height (1 m). The correct calculation yields a potential energy of 9800 joules. The discussion emphasizes the direct relationship between height and gravitational potential energy, confirming that lifting a mass increases its potential energy. Proper application of the formula is essential for accurate results.

If a 1000 kilogram car is lifted 1 meter what is its potential energy
with respect to the floor?

I used the following to solve,
PE = mgh

1000 * 1 + 1000PE

Is this the correct formula for solving for PE.

I am confused with the relationship potential energy and height.

The higher you lift a mass, the more gravitational potential energy you have.

Your answer is incorrect.

You start correctly with PE = mgh.

m = mass
g = acceleration due to gravity (9.8 m/s^2)
h = height.

All you need to do is plug the numbers you have into the equation.
 
thanks I feel a sleep on the job, again.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
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 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
