1) An object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by an external force.
2) Inertia is the tendency of an object to resist changes in its motion. According to Newton's First Law, an object with more mass will have more inertia.
3) The concept of momentum is related to Newton's First Law. An object with a larger mass will have a greater momentum if it is moving at the same speed as an object with a smaller mass.
4) Newton's First Law explains why seat belts are important in cars. In the event of a sudden stop or collision, the seat belt applies an external force to prevent the occupants from continuing to move forward with the same speed and direction.
5) The reason we feel a backward push when a moving vehicle suddenly stops is due to Newton's First Law. Our body, which was moving forward with the same speed and direction as the vehicle, tends to keep moving until an external force (e.g., the seat belt or friction) slows it down.
6) Astronauts experience weightlessness in space because there is very little air resistance and hardly any external forces acting on their bodies. Without external forces to slow them down, they continue to move with the same speed and direction as their spacecraft.
