Mass, weight, and gravity are related but distinct concepts. Mass is the amount of matter in an object and remains constant regardless of location. Weight is the force of gravity acting on an object's mass, and it can change depending on the gravitational field. Gravity is the force that attracts objects with mass towards each other.
Understanding the differences between these concepts is crucial in physics. Let's test your understanding with the following activities!
Match the terms with their definitions:
| Term | Definition |
|---|---|
| 1. Mass | A. The force of gravity acting on an object. |
| 2. Weight | B. The amount of matter in an object. |
| 3. Gravity | C. A measure of how hard it is to change an object's velocity. |
| 4. Inertia | D. The force that attracts objects with mass towards each other. |
| 5. Kilogram | E. The standard unit of mass in the metric system. |
(Match the numbers with the letters)
