General physics
conservation of angular momentum
Physics; General physics
If the net torque acting on a rigid body is zero, then the angular momentum of the body is constant or conserved.
conservation of momentum
Physics; General physics
The principle stating that for any isolated system, linear momentum is constant with time.
convex lens
Physics; General physics
Also called a converging lens, a lens that is thicker in the middle than at the edges. Convex lenses refract light through a focal point.
convex mirror
Physics; General physics
A mirror that is curved such that its center is closer to the viewer than the edges, such as a doorknob. Convex mirrors reflect light away from a focal point.
cosine
Physics; General physics
The cosine of an angle in a right triangle is equal to the length of the side adjacent to the angle divided by the length of the hypotenuse.
cross product
Physics; General physics
A form of vector multiplication, where two vectors are multiplied to produce a third vector. The cross product of two vectors, A and B , separated by an angle, θ , is A × B = ABcos θ ...
