From Newton’s first law of motion,
- a body can only undergo translational motion
- once a body remains at rest no force acts on it
-
the net force acting in uniform linear motion is zero
- a body's inertia is its weight
The correct answer is: C
Explanation
The key point of this law is that if there is no net force resulting from unbalanced forces acting on an object. If all the external forces cancel each other out, then the object will maintain a constant velocity.
