# How much work does it take to raise a 7 kg  weight 1 m ?

Work done is $68.6$ joules
Work done is Force multiplied by distance. As weight is $7 k g$ and distance is $1 m$, (it is assumed that force is applied against gravity $9.8 \frac{m}{s} ^ 2$, as the words 'raise' and 'weight' are used)
Work done = $7 \cdot 9.8 \cdot 1$ i.e. $68.6$ joules.
