Balancing the centripetal force mv^2/r with the force experienced due to motion in a magnetic field qvB: m = qBr/v = qBC/2piv (C circumference). Putting in numbers: m = 1.83e-23 kg (~11,000 mass of proton...

Firstly, let's remember Newton's laws which tell us that in order for something to change direction of motion - like: going around in a circle - a net force needs to be acting on the object. In the case o...

Newton's second law, F=ma, describes the relationship between an external force on an object F, the mass of the object m and the resulting acceleration of the object a. We can see that the acceleration of...

That is a good question. F=ma is a special case of Newton's 2nd Law of Motion . Newton's second law states that: The rate of change of linear momentum is proportional to the applied force and acts in the ...

This is really just a definition! When we ask what the potential energy of an object is, we are really asking what energy is available to be extracted. In the case of gravity: two objects separated by an ...
