Question

according to newtons first law, which characteristic of a moving object would remain constant if there were no other forces acting on it?
○ size
○ mass
○ shape
○ speed

Explanation:

Newton's first law (law of inertia) states that a moving object will maintain its state of motion (constant velocity, which includes constant speed in a straight line) if no net external forces act on it. Size, mass, and shape are inherent properties that do not relate to the object's motion state governed by this law.

Answer:

D. speed
