Question

If you push a box a distance of 2,000 meters with a force of 1 newton, how many Calories have you used?

1 Calorie= 4,187 Joules

Answer 1

Work = F*d = 1 * 2000 = 2000 Joules.

Calories = 2000J * 1cal/4.184J = 478

Answer 2

.478

Answer 3

If you push a box for a distance of 1 meter with a force of 4.187 newtons, how many calories have been used?

Answer 4

You would do w= f*d, so it would end up being 1 N * 2,000m = 2,000 J. Then, you would divide it by 4,187 (1 C = 4,187 j) to get 0.478 Calories.
