All About Physics?

2. Unit of electrical charge. Charge caused by flow of one ampere for one second.
6. the distance travelled in a particular direction from a specified origin
7. A diagram/bookkeeping device that helps in conceptualizing and calculating interactions between particles in spacetime
9. He developed the general theory of relativity, one of the two pillars of modern physics.
10. Force opposing relative motion of two objects are in contact.
12. Condition in which net force is equal to zero. Condition in which net torque on object is zero.
14. Aparticles are just electrons that come from the nucleius when a neutron changes into a proton.
15. Ratio of potential difference across device to current through it.
17. The force of gravity on a body.

1. Antiparticle equivalent of electron.
3. Light that generally comes from the electrons in very hot object.
4. Device used to measure very small currents.
5. Professor of this Physics course/this online course.
6. One of the scalar versions of velocity and displacement.
8. Device that changes force needed to do work.
9. It is a light and its relatives, from short wave length to long wavelength:
11. Are made up of neutrons and protons, n and p.
13. Atomic nuclei having same number of protons but different numbers of neutrons.
16. Non-material property capable of causing changes in matter.
17. Power- the rate of doing work;unit of power, one joule per second.
