sir when we climb up a rope with acceleration how do tension helps in that please explain

1. Use Newton’s laws of motion and free body diagrams. When we are at rest or moving up or down without acceleration, our weight will be equal to T.
But when moving with acceleration, it will be different. While climbing up with acceleration, ma = T-mg
or T = m(a+g)

6. devender sharma says:

when we climb up then rope is very tight because of our weight. then tension is greater than weight so climb. there ma=T-mg (because tension is greater)you right admin
