Asked by danny
calculate the horizontal force that must be applied to a 1-kg puck to make it accelerate on a horizontal friction-free air table with the same acceleration it would have if it were dropped and fell freely?

F = M a
Since (horizontal) acceleration a = g, you need a force equal to the weight,
F = M g = 9.8 Newtons
Since (horizontal) acceleration a = g, you need a force equal to the weight,
F = M g = 9.8 Newtons
