### Vectors

A vector can be pictured as a directed line segment with the vector's magnitude and the arrow indicating the direction. Formulas used to solve numerical vectors are given below.

### Kinematics

Kinematics is a subdivision of classical mechanics like the motion of a body or system of bodies without forcing involved Formulas used to solve kinematics are given below. These formulas will help you in your Physics class 11th exam.

### Projectile Motion

Projectile motion is the motion of an object thrown into a direction in the air. It is used to measure gravity. Formulas used to solve projectile motion are given below. These Physics formulas class 11th will help you with your Physics exam and competitive exams.

### Work, Power and Energy

Work done means the force is applied while energy is used, and power can be defined as work done per unit time. Formulas used to attempt problem-solving questions on work, passion, and life are below. These formulas will help you in your Physics class 11th exam.

**a. Work**

Definition: In Physics, work is said to be done whenever a force applied to an object, makes the object move.

Formula: Work is calculated by the product of applied force and the displacement of the object.

W = F × d

Unit: The SI unit of work the joule (J), also 1J = 1 Nm (newton-meter)

**b. Energy**

Definition: Energy is defined as the capacity of a body to do work.

Formula: The formula potential energy is given by:

P.E. = mgh

The formula for kinetic energy is given by:

K.E. = ½(mv²)

Unit: The SI unit of energy is the same as that of work, and it is joule (J), this unit is named in honour of an English physicist Sir James Prescott Joule.

**c. Power**

Definition: Power can be defined as the rate at which work is done i.e. energy converted.

Formula: The formula for power is

P = W/t

Unit: The unit of power is Watt (W).

### Gravitation

Gravity is a natural phenomenon by which all things with mass or energy are brought towards one another, including stars, planets, galaxies, and even light. Formulas used to solve numerals on gravitation are given below:

### Waves Motion

Wave motion happens when the energy is transferred from one point of the medium to another without an actual transport of matter between two points. Formulas used to solve wave motion numerals are given below:

### Sound Wave

The sound waves are the waves that are generated by a useful source. Formulas used to solve multiple numerical sound waves are given below. These formulas will help you with your Physics section in competitive exams and perform well.

### Reflection of Light

Reflection happens when light bounces off an object. For example, when the surface is shiny and smooth like glass, or polished metal, the light reflects the same angle as it hits the surface. Formulas used to solve the numericals on reflection of light are given below:

### Heat and Temperature

Heat is energy transferred from one body to another, and the temperature is a measure of heat or cold. Formulas used to solve heat and temperature are given below. These formulas will help you with solving numerical easily.

### Specific Heat

Specific heat is the ratio of the quantity of heat required to raise a body's temperature one degree of what is necessary to raise the temperature of an equal mass of water one degree. Formulas used to solve numerical on specific heat are given below:

### Photoelectric effect

Photoelectric effects occur when electrically charged particles are emitted from or within a material when it receives electromagnetic radiation. Formulas used to solve the photoelectric effect are given below:
