What you'll likely be quizzed about
- Newton's first law states that an object at rest stays at rest and an object in motion stays in motion at a constant speed and in a straight line unless acted on by a net external force.
- This principle emphasizes the concept of inertia, which is the tendency of an object to resist changes in its state of motion.
- Therefore, forces must be applied to overcome inertia.
