question 1
in physics, work is defined as the product of the
net force and the displacement.
net force parallel to the motion and the displacement.
net force parallel to the motion and the time it is applied.
applied force and the displacement.

Explanation:

Work in physics is calculated as \( W = F_{\parallel}d \), where \( F_{\parallel} \) is the component of the net force parallel to the motion (displacement direction), and \( d \) is the displacement. The formula does not involve time (eliminating the time - related option). It's about the net force component parallel to motion (not just any applied force or total net force without considering direction).

Answer:

net force parallel to the motion and the displacement.
