\cdot or, direct cross product is better than asterisk
Find position of a particle at a time
• If we have a force which changes depending on the position of a particle, how can we find the position of the particle at some time $t$?
• We can find its velocity if it has travelled a given distance
• $$\int^{r_f}_{r_o} F(r)dr = \frac{1}{2} * m_p(u_f^2 - u_o^2)$$
• but this equation doesn't involve time and I don't see how we can 'generate' time from a position varying force. Any help?

Typeset equation using inline Mathjax instead of as image, plus minor formatting and copy-editing
