Answer:
Basic Physics Formula
a = \frac{v-u}{t}
\rho = \frac{m}{V}
P= \frac{W}{t}
P= \frac{F}{A}
E = \frac{1}{2}mv^2.
f= \frac{V}{\lambda}
Some Important Formulas:
Area of the rectangle, A = L \times B. Area of the square, A =Side ^2. Perimeter of a rectangle, P = 2 \times ( L+B ) Perimeter of square, P = 4 \times Side.
Main topics covered in this part of CBSE Class 9 Science, Motion: Chapter Notes, are: Three Equations of Motion.
In other words, the dimensions of a physical quantity are the powers to which the base quantities (fundamental quantities) are raised to represent that quantity. ... Therefore, [V] = [L3] That is, the dimension of volume is 3 dimension in length and zero in mass and time.
The seven SI base units, which are comprised of:
Length - meter (m)
Time - second (s)
Amount of substance - mole (mole)
Electric current - ampere (A)
Temperature - kelvin (K)
Luminous intensity - candela (cd)
Mass - kilogram (kg)
