INTRO TO PHYSICS
Across
- 6. The unit of frequency, also known as cycles per second.
- 7. The number of oscillations completed in 1 second by an oscillating body.
- 8. The product of force and time for which force acts, also equal to the change in momentum.
- 9. The shortest distance between the initial and final position of a moving body. It is a vector quantity.
- 10. The total amount of energy radiated each second from the surface of a source.
- 11. The actual path length covered by a body. It is a scalar quantity.
- 13. The unit of work and energy.
Down
- 1. For a given mass of a gas at constant pressure, the volume is directly proportional to the temperature.
- 2. The rate of change of velocity with respect to time.
- 3. The mass of a substance per unit volume.
- 4. The point to which rays that are initially parallel to the axis of a lens or mirror are converged or from which they appear to diverge.
- 5. The gravitational attraction at the surface of a planet or other celestial body.
- 12. of reflection The angle between the reflected ray and the normal.
