The Principle of Moments - A Level Physics

This video introduces and explains the principle of moments for A Level Physics.

Apply a force at a distance and you have a turning effect which we call a moment. I show you how to calculate the moment when a force acts at an angle. Finally, for an object in rotational equilibrium the sum of the anti-clockwise and clockwise moments is zero. This is the principle of moments.

Thanks for watching,

Learnt more in this than a 6 hour lesson

You're really good man. Keep it up!

Will a force parallel to the lever and have perpendicular distance from the pivot produce moment?

[paolariemer]

You explained it very well! Thank you!

[darcy]

Would you please do a few videos breaking down the substituting formulas in the multiple-choice questions that involve algebra. Some are so tricky, and nobody seems to break the math down.
Hope I make sense.

Thanks for the explanation.From Papua New Guinea 🇵🇬.

Why does the theta in the pivot the same in the force actiing on it? Im a noob help:'(

[jeffjeffson]

5:37 Why can we ignore the horizontal component of the force?

[abschy]

Could you give real Values instead because the letters confuse me on which are the actual unknowns (what you're trying to work out)!

At 3.15 why is theta next to the pivot??
