What is the work of gravity when lifting a 5 kg load to a height of 6 m?

To find the value of the work of gravity when lifting the specified load, we apply the formula: A = Ft * S * cosα = mg * g * h * cosα.

Variables and constants: mg – weight of the cargo (mg = 5 kg); g – acceleration due to gravity (g ≈ 10 m / s2); h – height, movement of the load (h = 6 m); α is the angle between the movement of the specified load and the gravity vector (α = 180º).

Calculation: A = mg * g * h * cosα = 5 * 10 * 6 * cos 180º = -300 J.

Answer: The work of gravity when lifting the specified load is -300 J.
