... Now we use: ax = dvx/dt and ay = dvy/dt. Since is not constant, we need to use the product rule: ax = dvx/dt = d[- r sin(q) ]/dt = r d[-]/dt sin(q) + - r d[sin(q)]/dt = -a r sin(q) + -2 r cos(q) . In a similar way, we get: ay = +a r cos(q) + -2 r sin(q) . ...

... When the force is at an angle When a force acts in a direction that is not in line with the displacement, only part of the force does work. The component of F that is parallel to the displacement does work, but the perpendicular component of F does zero work. So, a more general formula for work is ...
