PHYSICS

5. When two waves overlap in a medium, this occurs.
6. It is determined by adding together point by point the displacements of the individual component waves.
8. The net gravitational force exerted on an object by all other bodies in the universe.
9. It is a disturbance that transfers energy from one point to another without imparting net motion to the medium through which it propagates.
10. The SI unit of frequency.
11. Action-at-a-distance forces can be explained using the concept of what?
16. The line through the fixed point of a rotating object.
17. The time it takes to complete one cycle.
18. involves bodies moving along a straight line.
19. The tendency of the applied force to rotate the object depends on the magnitude of the force.
20. Along which the force vector lies.

1. A wave in which the particles move in a direction perpendicular to the direction of the propagation of the wave.
2. A wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
3. The reciprocal of the period.
4. It is a substance or material where the waves travel from one point to another.
7. It is a non-contact force.
12. A very good example of electromagnetic waves.
13. The change in momentum.
14. Involves a body rotating about an axis that is stationary with respect to an inertial frame of reference.
15. The tendency of an object to resist changes in its rotational motion about an axis.
