Hi Doc Al,
When considering the forces, how come we did not consider the minus sign in Hooke's law? So when we consider the spring force (whether we take up or down being positive), is the spring force just "kx"? Depending on the direction we take as positive/negative will dictate then the...
Hello!
I am having trouble with a simple concept...trying to figure out the signs of net force of a mass on a spring.
I understand that for a mass on the spring, there is a downward force of gravity (mg) and upwards restoring force of the (-kx). How do we equate these, if we regard the...
