Question

based on what was taught in lab this week, which newtons law of motion explains why elbows should not be locked during palpations/adjustments?

a) 1st

b) 2nd

c) 3rd

d) 4th

Explanation:

Newton's 3rd law states that for every action, there is an equal and opposite reaction. When performing palpations or adjustments, if the elbow is locked, the force applied (action) will have an equal and opposite reaction force transmitted back, which can cause injury. Newton's 1st law is about inertia, 2nd about force and acceleration ($F = ma$), and there is no 4th law of motion (Newton has three laws of motion). So the correct law is the 3rd.

Answer:

c) 3rd
