# Basic Physics Formula

Physics is all about articulating the things with real values and not memorizing them up. During applications, we may come across many concepts, problems, and mathematical formulas. With these, we have to use our ability and creativity and good sort of potential to find solutions. Here we will have some basic physics formula with examples. Let us learn!

## Basic Physics Formula

Some basic but very important Physics formula is given below:

### 1) Average Speed Formula:

The average speed is the average of speed of a moving body for the overall distance that it has covered.

S = $$\frac{d}{t}$$

Where,

 S Average speed d Total distance traveled t Total time is taken

### 2) Acceleration Formula:

Acceleration is defined as the rate of change in velocity to the change in time. It is denoted by symbol a.

a =$$\frac{v-u}{t}$$

where,

 a Acceleration v Final Velocity u Initial Velocity t Time taken

### 3) Density Formula:

The density of material shows the denseness of it in a specific given area.

$$\rho = \frac{m}{V}$$

Where,

 $$\rho$$ Density m Mass of the body V The volume of the body

### 4) Newton’s Second Law:

According to Newton’s second law of motion, the force can be expressed by the product of mass and acceleration of the body.

F = m ×  a

Where,

 F Force m Mass of the body a Acceleration in velocity available

### 5) Power Formula:

The capacity to do some work is termed as Energy. The Energy spent to do work in a unit amount of time is termed as Power.

P=$$\frac{W}{t}$$

Where,

 P Power W Work done t Time taken

### 6) Weight Formula:

Weight is not anything but the force which an object experiences due to gravity.

W=mg

Where,

 W Weight m Mass of the body g Acceleration due to gravity

### 7) Pressure Formula:

The pressure is defined as the amount of force applied per unit area of the object.

P=$$\frac{F}{A}$$

Where,

 P Pressure F Force applied A Total Area of the object

### 8) Kinetic Energy formula:

Kinetic energy is the energy that is possessed by a body due to its state of motion.

E = $$\frac{1}{2}mv^2$$

Where,

 E Kinetic Energy m Mass of the body v The velocity with which the body is traveling

### 9) Ohms Law Formula:

Ohms law says that the current running through some conductor material is directly proportional to the potential difference between two endpoints of the conductor.

V= I × R

Where,

 V Voltage measured in Volts I Electric current flowing through the conductor in amperes. R The resistance of the material in ohms.

### 10) Frequency Formula:

Frequency is the revolutions completed per second or as the number of wave cycles.

f= $$\frac{V}{\lambda}$$

Where,

 f Frequency of the wave V Velocity or wave speed $$\lambda$$ The wavelength of the wave

## Solved Examples

Q.1: A car is traveling with a velocity of 10 m/s and it has a mass of 250 Kg. Compute its Kinetic energy?

Solution:

As given here,

Mass of the body, m = 250 Kg,

Velocity of it, v = 10 m/s,

So Kinetic energy will be as:

E = $$\frac{1}{2}mv^2$$

E = $$\frac{1}{2}\times 250\times10^2$$

= 125 ×100

E = 12500 joules

Therefore, kinetic energy will be 12500 joules.
