In physics, the law of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it. In simpler terms, in a collision, the total momentum before the collision is equal to the total momentum after the collision. When we're dealing with collisions in two dimensions (2D), we need to consider the x and y components of the momentum separately. This lab activity helps verify this principle by analyzing collisions of objects on a 2D plane.
Essentially, you'll be measuring the velocities and masses of objects before and after they collide, and then calculating the total momentum in both the x and y directions. By comparing the 'before' and 'after' momentum values, you can verify if momentum is conserved within experimental error. It's a cool way to see physics in action!💥
Match the term with its correct definition:
| Term | Definition |
|---|---|
| 1. Momentum | A. A collision where kinetic energy is conserved. |
| 2. Elastic Collision | B. A collision where kinetic energy is not conserved. |
| 3. Inelastic Collision | C. A measure of an object's mass in motion. |
| 4. Conservation | D. A force acting on an object for some interval of time. |
| 5. Impulse | E. The principle stating a particular physical property remains constant. |
