$\bf \huge \: Answer \: \:$

1) Average Speed Formula:

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

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

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.

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

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.

$\bf \rho = \frac{m}{V}ρ= \: \:$

Where,

$\bf \: \rhoρ Density$

1. 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.

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

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.

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

• 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.

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

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.

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

Answer 2

Answer:

${\huge{\underline{\underline{\mathfrak{\red{Answer:-}}}}}}$

∆x = displacement vf = final velocity ∆t = elapsed time a = acceleration Use this formula when you don't have vi. vf = final velocity vi = initial velocity a = acceleration ∆x = displacement Use this formula when you don't have ∆t. ... p = momentum m = mass v = velocity The definition of momentum.
