I want to learn physics. Where should I start?
I’m here to help you see that you can do Physics!
Have you had any lessons at all in school that you can work from? Learning is about taking time, (lots of time) and revisiting what you have been taught. Identify what you understand and what you don’t understand. Practice what you do understand until you can do it without looking up the answer. Then ask for help with what you don’t understand.

A toy car slides down a slope. If the top of the slope is 2m higher than the foot of the slope, how fast will the car be moving when it reaches the foot? (Assume that all of its g.p.e is transformed to k.e?
Hi! In this question, we can use the change in gravitational potential energy to calculate the kinetic energy that the car will have at the foot of ...

How do you calculate theoretical deflections for an experiment on unsymmetrical bending of a cantilever beam & what are the units to be used for young's modulus, length, force and 2nd moment area of used for the equation used to calculate deflection?
All this depends on the cross section of the cantilever and how it is supported then you build the theoretical model. Units of Young’s Modulus are P...
