1. The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
2. Newton’s first law is also known as the law of inertia.
3. A moving object will continue moving at a constant velocity unless acted upon by an unbalanced force.
4. An object at rest will remain at rest unless acted upon by an unbalanced force.
5. Inertia is the tendency of an object to resist changes in its state of motion.
6. The greater the mass of an object, the greater its inertia.
7. When you are riding in a car and it suddenly stops, your body tends to keep moving forward due to inertia.
8. Seat belts help prevent injury by restraining your body during sudden stops or collisions.
9. If you slide a book across a table, it eventually stops because of friction, which is an unbalanced force.
10. In space, far from any gravitational influence, an object set in motion will continue moving indefinitely at a constant speed and direction.
11. A soccer ball kicked on a field slows down and stops because of friction with the grass and air resistance.
12. In the absence of external forces, an object’s velocity remains constant.
13. A heavy truck has more inertia than a small car, making it harder to start or stop.
14. When a magician pulls a tablecloth out from under dishes, the dishes remain in place due to inertia.
15. Newton’s first law explains why objects do not change their motion without a force acting on them.
16. A rolling ball on a smooth surface will roll farther than on a rough surface because there is less friction.
17. Inertia is not a force; it is a property of matter related to mass.
18. Astronauts floating in space experience weightlessness but still have inertia.
19. A passenger in a turning car feels pushed outward because their body wants to continue moving in a straight line.
20. The law of inertia applies to all objects, whether they are on Earth or in space.
