Physics Revision

2. Motion of an object that is no undergoing acceleration.
3. The minimum frequency of a photon that can eject an electron from a surface.
6. A non accelerating frame of reference in which Newton's laws of motion hold.
8. Regions of space around the nucleus of an atom where an electron is likely to be found.
10. The force acting along an imaginary line drawn perpendicular to the surface.
12. Demonstrates the wave nature of light by allowing two coherent beams of light to overlap on a screen to form an interference pattern.
13. The capacity to do work in which it is transformed or transferred.
16. A single vector that is a combination of two or more other vectors.
18. An object that absorbs all incoming radiation at all wavelengths; it is a perfect absorber or emitter of radiation.
20. A particle composed of quarks and gluons.
22. the length as measured by an observer at rest with respect to the object.

1. The relation between two events assumed to be happening at the same time in a frame of reference.
4. The force of attraction between objects with mass.
5. A depiction of the influence of a vector in a given direction.
7. A variable quantity, such as force, that has both magnitude and direction.
9. The product of an object's mass and velocity.
11. The number of waves that move past a given point in one second.
14. The smallest discrete packets of energy of electromagnetic waves, also later known as photons.
15. The process that occurs when a subatomic particle collides with its respective antiparticle to produce other particles such as a photon.
17. The third strongest force of the four fundamental forces. It is mediated by the W and Z bosons.
19. Individually separate and distinct.
21. A law that states that the direction of an induced electric current is such that it produces a current whose magnetic field opposes the change in the circuit that produced it.
