According to Newton's second law of motion, the net force on an object moving upward with acceleration $a$ is the result of the upward tension ($T$) overcoming the downward weight ($mg$).

The equation of motion is: $T - mg = ma$ $T = m(g + a)$

Given: Mass, $m = 1000 \text{ kg}$ Acceleration, $a = 1 \text{ m/s}^2$

• Acceleration due to gravity, $g = 9.8 \text{ m/s}^2$ (standard value)

Substituting the values: $T = 1000 \text{ kg} \times (9.8 \text{ m/s}^2 + 1 \text{ m/s}^2)$ $T = 1000 \times 10.8 \text{ N}$ $T = 10,800 \text{ N}$

(Note: This concept relates to apparent weight in a lift and effective gravity as seen in Source 73 and 126).
