WebOct 27, 2024 · $\begingroup$ It's called a lever :) Of course, the force acting on the object to be lifted still needs to be exactly equal to the weight of that object - otherwise it will accelerate (up or down). Lifting usually means applying a larger force for a while (to get the object to move), and then maintaining constant force equal to its weight (to either keep … WebAug 18, 2024 · So, for the force of gravity, you can write: #F_g=mg# where #g# is just #9.8"m"//s"^2# And as long as you remember that the force of gravity points downward, you know that, as a force, it should be negative. The magnitude will always be positive regardless, so g is still used and not -g.
