Bicycle physics

From a long time, I have a question that bicycle is not stable at low speed or for that matter it's difficult to balance bicycle on its wheels in static position ( with zero speed and no brakes). Can ...

How to find the initial speed on the y axis while only having Dy, Dx, angle, and acceleration

Is it possible to find the initial speed of a projectile on the y axis while only having $D_y$ (distance on the y axis), $D_x$ (distance on the x axis), the angle and $a_y$ (acceleration on the y axis)...

electric field inside the surface with light is at normal incidence

I read that at normal incidence the polarizations of sigma and pi are indistinguishable so how can I find the electric field then if I cannot use either case's equations? Also if the light is from air ...

Given acceleration, why must kinematics be used when solving for distance in terms of time rather than the literal definition of acceleration?

I'm working with rotational motion, and one of the mistakes that I made in solving for distance in terms of time was substituting angular acceleration for (d/Rt^2) where d is distance and R is the ...

If space-time can be warped or curved, Doesn't that mean that It need space to be curved?

There is a doubt that i've always have and no one has given to me a satisfing or good response, i hope someone give me the response. Lets Talk about space only. If space can be curved or warped, that ...
