Translational motion

Physics; General physics

The movement of a rigid body's centre of mass in space.

Tip

Physics; General physics

In the graphical representation of vectors, the tip of the arrow is the pointy end.

Unit vector

Physics; General physics

A unit vector is a vector with length 1.

Boiling

Physics; General physics

A state of liquid at boiling point temperature, maximum vapour pressure is equal the external pressure around that liquid.

Apparent depth

Physics; General physics

Depth that a transparent material such as water or glass appears to have when viewed from above. This is less than its real depth because of the refraction. The ratio of the real depth to the ...

Annihilation radiation

Physics; General physics

The radiation emitted from colliding between a particle and its anti-particle, such gamma ray will emit in opposite direction when electron collides with positron.
