Question

sph3u1 - newtons laws mcq (20 questions)

1. newtons first law describes an objects tendency to:

a. speed up
b. slow down
c. resist changes in motion
d. move in circles

Explanation:

Newton's First Law of Motion, also known as the law of inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This means the law is about an object's tendency to resist changes in its state of motion. Options A (speed up) and B (slow down) relate more to Newton's Second Law ($F = ma$ which involves acceleration, i.e., change in speed). Option D (move in circles) is related to centripetal force concepts rather than the core of Newton's First Law.

Answer:

C. Resist changes in motion
