1. What is the relationship between motion and forces?

Question

2. What is Newton’s first law of motion? What does it mean?
3. What is inertia? How does it relate to mass?
4. What are inertial forces?
What is one Newton equal to?

Answer each answer in order, answer in very short sentences and make it very understandable and reasonable

Answer 1

1. Motion is the change in position of an object, while forces are the pushes or pulls that cause or change that motion.

2. Newton's first law of motion states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force. This means that unbalanced forces are needed to change an object's state of motion.

3. Inertia is the property of an object that resists changes in its motion. It is directly related to mass; greater mass means greater inertia.

4. Inertial forces are apparent forces that arise in a non-inertial (accelerating) reference frame. They seem to act on objects when viewed from that frame, like the feeling of being pushed back in a car that accelerates.

5. One Newton (N) is equal to the force required to accelerate one kilogram of mass by one meter per second squared (1 N = 1 kg·m/s²).
