Homework Statement
When an elevator moves upwards with an acceleration, what is the equation for tension?
Is it T+W =ma?
When an elevator moves downwards with an acceleration, would the equation be
T+W=-ma?
Thats all. Thanks.
I really can't figure it out. All I know is that the equations T-mg=ma (for upwards) and T-mg=-ma (downwards) are wrong.
