Answer:
Using an object of less mass can reduce the energy lost due to friction.
Explanation:
let the mass of the object be M.
acceleration due to gravity be g, coefficient of kinetic friction between object and slider be , angle between horizntal and slider be ∅ and distance slided by the object be d.
work done by friction of the ramp will be the energy lost by ramp due to friction.
work done = force×displacement
force = ×M×g×cos∅
displacement= d
therefore work done = ×M×g×cos∅×d
therefore on decreasing the mass M we can see that work done by friction decreases so the energy lost due to friction also decreases.
