I was doing a question and it said that there was a string attached to the block which is on a smooth plane, at 30 degrees to the plane, how wouk i work out the tension in the string?
Instead of the F = mg*sin(theta) can we say F = mg/sin(theta)? Taking the angle of the slope as (15deg) and taking (mg) as the opposite and taking F as the hypotenuse?
Thanks for trying to save my physics a level grade
This video used to be handwritten - nice upgrade!
A big fan of your work
At 5:00 why wont the reaction force be -mg cos theta
their magnitudes are equal
My ext 2 mark after this video 📈📈📈
thanks
please solve past papers for physics 9702 , your work is much appreciated
I don't really understand the upward and downward acceleration, everything else is fine.

Nope
if an object (e.g a bike) is moving up the slope at a constant speed, what does that make mg sin theta equal to? (if anything)
The force of the cyclist pushing up the slope 😊
@@ScienceShorts the force of the cyclist + the weight of the person and the bike right??
@@robinsghost1250 The force of him pushing is the same as the force of their combined weight
i love you
Does a level surface have slope?
Level surface means totally horizontal so it doesn’t have a slope
you lost me when you added angles
