What is the formula for motion?
Newton’s second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
What is the S in physics?
s = displacement (vector version of distance)
What does δ mean in physics?
In general physics, delta-v is a change in velocity. The Greek uppercase letter Δ (delta) is the standard mathematical symbol to represent change in some quantity.
What does K mean in physics?
Boltzmann constant
What is big K in physics?
The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. It was named after the French physicist Charles-Augustin de Coulomb (1736–1806) who introduced Coulomb’s law.
What does N stand for in physics?
newton
How do you find N in physics?
The definition of a Newton, the standard unit of force, is N = kg * m/s^2.
What does the symbol N mean?
List of Mathematical Symbols • R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers.
What is V and U in light?
Where v is the image distance and u is the object distance. Hence, the expression for magnification (m) becomes: m = h’/h = -v/u. Learn more about Reflection of Light here.
How are U and V related?
if v is the image distance and u is the object distance. It can be also defined as the ratio of the height of the image to the height of the object.
What is 1 f 1 v 1 u?
Derive the lens formula, 1/ f = 1/v – 1/u for a concave lens, using the necessary ray diagram. Derivation of len’s formula : Len’s formula gives us the relation between focal length of a lens and distances of object and image from the optical centre of the lens.
What is the formula of plane mirror?
The Mirror Equations f=R/2 or f=∞ for a plane mirror.
What is the normal to a plane mirror?
A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of the incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface).
What is Mirror formula in physics?
A mirror formula can be defined as the formula which gives the relationship between the distance of object ‘u’, the distance of image ‘v’, and the focal length of the mirror ‘f’.
How does a plane mirror work?
Plane mirrors work because the light rays create a virtual image behind the mirror. Light rays from the object strike the mirror and reflect according to the law of reflection. Therefore, our eye and brain track the light rays backward to a position from which they appear to have come.
What are the characteristics of a plane mirror?
An image formed by a plane mirror has the following characteristics:
- Virtual and erect.
- Behind the mirror.
- The size of the image is equal to the size of the object.
- Laterally inverted image (image of the left side visible on the right side).
What are two types of mirror?
Common Types of Mirrors
- Plane Mirror — These are flat mirrors that reflect images in their normal proportions, reversed from left to right.
- Concave Mirror — Concave mirrors are spherical mirrors that curve inward like a spoon.
- Convex Mirror — Convex mirrors are also spherical mirrors.
How is the position of image related to the position of object?
The image formed in a plane mirror is at the same distance behind the mirror as the object is in front of the mirror. That is, the position of the image and object are at the same distance with respect to the mirror but on its opposite sides.
What is the radius of curvature of a plane mirror?
infinite
