## What is First Equation of Motion

The first equation of motion is V = U + AT . Here, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time. The velocity-time relationship gives the first equation of motion and can be used to find acceleration. Similarly, what is the third equation of motion? The third equation of …

## How do you find the initial velocity

Let us know about How do you find the initial velocity. If you know the values ​​of distance, time, and acceleration, you can use the following equation: Initial Velocity: V i = (d / t) – [(a * t) / 2] Understand what each symbol means. v i u201Cinitial velocityu201d d means u201cdistanceu201d a means u201ccelerationu201d t means u201ctimeu201d Similarly, …

## Formula for Weight

Come friends, today we will know how much is Formula for Weight. let’s start. The general formula for finding weight is given as, W = mg (N/kg) . Here ‘g’ denotes acceleration due to gravity. The value of g on Earth is 9.8 m/s. is 2 . It is also known as the gravitational constant. Also, what is the weight formula? Weight is …

## Volume of The Earth

Let us know about Volume of The Earth. “Volume” is a measure of the amount of space occupied by an object. … Earth’s volume is approximately 1,083,206,916,846 cubic kilometers (259,875,159,532 cu mi) . According to some astronomers, about 1.3 million Earths could fit inside the Sun. Also, how many liters is an average human being? The average volume of …

## Unit of Volume

Let us know about Unit of Volume. Volume is the measure of the 3-dimensional space occupied by matter, or surrounded by a surface, measured in cubic units. The SI unit of volume is the cubic meter (m 3 ) , which is a derived unit. Similarly, how do you calculate volume from mass? Volume is equal to mass divided by density ; And. Mass …

## 3 Types of Acceleration

Let us know about 3 Types of Acceleration. There are three types of acceleration in physics, speed, direction and change in both simultaneously . The term “velocity” is often used in place of speed. One can calculate the acceleration of an object by determining its velocity and the period of its acceleration. (3 Types of Acceleration) Also, how do …

## Constant for Gravity

Let us know about Constant for Gravity. The value of G in SI units is 6.67 × 10 – 11 Newton kg – 2 m 2 . The direction of force is in a straight line between the two bodies and is attractive. Also, what is the value of G? Its value is 9.8 m/ s 2 on Earth. That is, the acceleration of gravity on the surface of …

## Formula for Mass

Let us know about Formula for Mass. Mass is always constant for a body. One way to calculate mass: Mass = Volume × Density . Weight is a measure of the force of gravity acting on a mass. The SI unit of mass is “kilogram”. Also, what is the unit in quantity? Volume is the measure of the 3-dimensional space …

## What Is the Difference Between Speed and Velocity

Let us know about What Is the Difference Between Speed and Velocity. Speed ​​is the time rate at which an object is moving along a path, whereas velocity is the rate and direction of motion of an object . for example, 50 km/h (31 mph) describes the speed at which a car is traveling along the road, …

## SI unit of speed

Let us know about SI unit of speed. The speed of an object is the distance the object travels in a unit time. The formula for speed is: Speed ​​= Distance time. The most common units of speed are meters per second (m/s) , kilometers per hour (km/h) and miles per hour (mph). Also, what is the difference velocity …
