Question

the amount of work done depends on the
a amount of force applied.
b mass and distance the object moves.
c mass and speed with which the object moves.
d amount of force and distance the object moves.

Explanation:

To determine the factors affecting work done, recall the physics formula for work: \( W = F \times d \) (where \( W \) is work, \( F \) is force, and \( d \) is distance in the direction of the force).

• Option a: Only force is insufficient, as distance is also needed.
• Option b: Mass is not a direct factor in the work formula (work depends on force, not mass directly, unless force is related to mass via \( F = ma \), but the formula for work is \( F \times d \)).
• Option c: Speed and mass are related to kinetic energy, not work (work is about force and distance, not speed).
• Option d: Matches the work formula \( W = F \times d \), as work depends on the amount of force applied and the distance the object moves in the direction of the force.

Answer:

d. amount of force and distance the object moves.
