Question 1 • Physics

In which scenario is the least amount of work done on a crate?

Answer
A
A force of 115 N moves it 26 m.
B
A force of 120 N moves it 25 m.
C
A force of 130 N moves it 22 m.
D
A force of 125 N moves it 27 m.

Explanation

Work is force multiplied by distance when the force acts in the direction of motion. The choices give: A, 120 × 25 = 3,000 J; B, 125 × 27 = 3,375 J; C, 130 × 22 = 2,860 J; and D, 115 × 26 = 2,990 J. The smallest amount is 2,860 J, so the answer is C, a force of 130 N moving the crate 22 m.
