Man, Physics is so interesting.

Ok so I just learned about magnetism and magnetic fields and and moving charges. the formula my professor gave me in class was Bp=μ/4∏ (Qa*Va x r (hat) / r^2 Can I somehow use that for Electric field instead?

So basically find the acceleration at multiple times and then average them?

I'm taking the second semester of General Physics at the college level. It's Physics P202. I haven't taken calculus yet.

Also aren't Kepler's laws for planetary motion?

My professor gave it to my class as a "project." When I asked him whether or not we should assume acceleration to be constant he said "that is something for you to decide." Which I'm assuming means yes because if we don't assume acceleration to be constant then there's no way that anyone in the...

Unfortunately I have not. Everything I've done so far has involved standard kinematic equations and assuming acceleration is constant. I've never done anything where acceleration isn't constant.

So the formula for a changing acceleration would be a= q1*q2/ k*d^2* m1? If I solve for acceleration using that formula, would I have to use different formulas to find the velocities and distance traveled or can I use the same ones I originally used? I appreciate your help

Ahh ok so is 1/4∏ε0 the same as k? In my physics class, the professor always gave us k as a constant of 9*10^9, but never told us where that came from.

What does ϵ0 represent?

Is there an equation for acceleration that isn't constant?

There are two electrically charged objects that are placed 6 cm away from each other. Each object has an electrical charge of +1 microColoumbs and a mass of 1 milligram. If one object is fixed in place, how far does the other go in 2 milliseconds? So I'm given the charge, distance between the...
