## What is the formula for GFS?

The formula is: weight/mass = gravitational field strength. On Earth the gravitational field strength is 10 N/kg.

## What is the x value of g?

Today, the currently accepted value is 6.67259 x 10-11 N m2/kg2. The value of G is an extremely small numerical value. Its smallness accounts for the fact that the force of gravitational attraction is only appreciable for objects with large mass.

What equals mass times gravity?

Weight
Weight is a specific force that is always equal to mass times acceleration due to gravity.

### What is the formula for mass with gravity?

To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G).

### What is the force of gravity in Newtons?

G represents the gravitational constant, which has a value of 6.674⋅10−11N(m/kg)2 6.674 ⋅ 10 − 11 N (m/kg) 2 . Because of the magnitude of G , gravitational force is very small unless large masses are involved.

How do you find the value of G’in free fall?

When the ball is released a timer is started. When the ball hits the trapdoor the timer is stopped. If the distance from the ball to the trapdoor is measured the acceleration due to gravity (g) can be calculated. Use the formula; s = ut + ½at² and note that u = 0 and a = g.

#### Who found the value of G?

Henry Cavendish
The first reliable measurement of G was made by Henry Cavendish in 1798! He calculated that G was equal to 6.754 10-11 newton-square meter per square kilogram (compared to today’s calculation of 6.67259).

#### Why is gravity 9.81 ms 2?

In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive. The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2.

How gravity is calculated?

On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg. Kilograms and slugs are units of mass; newtons and pounds are units of weight. Newton’s law of gravitation gives you the acceleration due to gravity near the surface of the Earth: 9.8 meters/second2.

## How mass is calculated?

Mass is always constant for a body. One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.

## Is mass equal to weight?

In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity. Objects on the surface of the Earth have weight, although sometimes the weight is difficult to measure.

What is the relationship between weight mass and gravity?

The connection between mass and weight is that the amount of force that gravity applies to an object is directly related to how much mass that object has. More mass = more force applied by gravity = greater weight.

### How does mass and weight relate to gravity?

The gravitational force between a mass and the Earth is the object’s weight. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: F g = mg.

### Does weight and mass depend on gravity?

Hence, the key difference between mass and weight is that mass does not depend on gravity, whereas weight depends on gravity. Thus, the mass cannot be zero, but weight can be zero if there is no gravity, i.e. in space, there is no gravity.

How do you calculate weight with mass?

Calculating Weight. Convert the mass from grams to kilograms by dividing the mass of the object by 1,000. For example, an object with a mass of 230.3 g would have a mass of 0.2303 kilograms. Write the formula for weight on your paper: w = mg. W stands for the weight of the object, m stands for the mass of the object,…
