3. What is the law of inertia? A.The overall force on an object when all the individual forces acting on an object are added together. B. The rate at which velocity changes. The state in which one object`s distance from another is changing. C. An object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force. D. Equal forces acting on an object in the opposite direction
Answer:
I think it's C
Explanation:
Hope it helps
Answer:
D not to sure if tama ako
Explanation:
inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.
