Question

1. when pushing or pulling an object, you are most likely to be injured trying to:

○ get the object moving
○ keep the object moving
○ test the object’s weight

Explanation:

To determine the answer, we analyze the physics concept of static and kinetic friction. Static friction (the force needed to get an object moving) is generally greater than kinetic friction (the force needed to keep it moving). So, trying to get the object moving requires more force, increasing injury risk. "Test the object’s weight" isn't related to injury risk from pushing/pulling.

Answer:

A. Get the object moving
