Question

1. to calculate work done on an object, ______. (1 point)

○ divide the distance the object moved by the force in the direction of motion
○ multiply the force in the direction of motion by the distance the object moved
○ multiply all forces applied to the object by the distance the object moved
○ divide the force in the direction of motion by the distance the object moved

Explanation:

The formula for work done ($W$) on an object is $W = F \times d$, where $F$ is the force applied in the direction of motion and $d$ is the distance the object moves. So we need to multiply the force in the direction of motion by the distance the object moved. The first option is dividing distance by force, which is incorrect. The third option considers all forces (but only the force in the direction of motion matters), so it's wrong. The fourth option is dividing force by distance, which is also incorrect.

Answer:

B. multiply the force in the direction of motion by the distance the object moved
