Question

What is Newton's first law of motion?

A. For every force there is an equal and opposite reaction force.
B. If a net force is applied to an object, then the object will accelerate.
C. An object will remain at rest or continue moving in a straight line with a constant speed unless acted on by an unbalanced force.
D. The gravitational force between two objects is proportional to their masses and inversely proportional to the distance between them.

Answer 1

C

Step-by-step explanation:

Newton's first Law of Motion is also known as law of inertia, which states that "an object at rest remains at rest, and an object that is moving will continue to move straight and with constant velocity, if and only if there is no net force acting on that object". As such, the correct option should be C.

Option A is Newton's third Law of Motion.

Option B is Newton's second Law of Motion

Option D is Newton's Law of Universal Gravity
