All About Physics?

3. One of the scalar versions of velocity and displacement.
4. Antiparticle equivalent of electron.
6. A diagram/bookkeeping device that helps in conceptualizing and calculating interactions between particles in spacetime
12. Condition in which net force is equal to zero. Condition in which net torque on object is zero.
13. Aparticles are just electrons that come from the nucleius when a neutron changes into a proton.
14. Atomic nuclei having same number of protons but different numbers of neutrons.
18. Device used to measure very small currents.
19. He developed the general theory of relativity, one of the two pillars of modern physics.
20. Are made up of neutrons and protons, n and p.

1. Ratio of potential difference across device to current through it.
2. Power- the rate of doing work;unit of power, one joule per second.
5. Unit of electrical charge. Charge caused by flow of one ampere for one second.
7. Non-material property capable of causing changes in matter.
8. Device that changes force needed to do work.
9. The area of total darkness in the shadow caused by an eclipse.
10. Force opposing relative motion of two objects are in contact.
11. the distance travelled in a particular direction from a specified origin
15. Light that generally comes from the electrons in very hot object.
16. The force of gravity on a body.
17. "My teacher calls himself"
