how much work is done in lifting a 8 kg box from the floor to a height of 2 m?​

blaireeeeeee · Answer

Work: Work is done when a force causes an object to move a certain distance. It's calculated as: Work (W) = Force (F) x Distance (d)Force due to Gravity: The force we need to overcome to lift the box is the force of gravity acting on it. This force is calculated as: Force (F) = Mass (m) x Acceleration due to gravity (g) where g = 9.8 m/s²CalculationsForce:F = m * gF = 8 kg * 9.8 m/s²F = 78.4 N (Newtons)Work:W = F * dW = 78.4 N * 2 mW = 156.8 J (Joules)
