The formula to calculate weight (W) is: W = m * g Where: W = weight in newtons (N) m = mass of the object in kilograms (kg) g = acceleration due to gravity (9.81 m/s^2 on Earth)
To calculate the buoyant force acting on an object submerged in water, you can use the formula: Buoyant force = Weight of the water displaced = Weight of the object in air - Weight of the object in water. This formula considers that the buoyant force is equal to the weight of the water displaced by the object.
To calculate buoyant force, you can use the formula: Buoyant force = weight of the fluid displaced by the object. This can be calculated using Archimedes' principle, which states that the buoyant force acting on an object is equal to the weight of the fluid that the object displaces.
To calculate weight on other planets, you can use the formula: Weight Mass x Gravity. The mass of an object remains the same, but the gravity on different planets varies. You can find the gravity of a planet by looking it up online or using a formula. Then, multiply the mass of the object by the gravity of the planet to find the weight on that planet.
To find an object's weight using a lever, you can use the principle of torque. By measuring the lengths of the lever arms on either side of the fulcrum, along with the distance from the object to the fulcrum, you can calculate the weight of the object. This is typically done using the formula: weight = force x distance.
To calculate upthrust force, use the formula: Upthrust force = Weight of fluid displaced - Weight of object. This force is present when an object is immersed in a fluid (liquid or gas) and experiences an upward force due to the displaced fluid pushing against it.

Object's density = (its mass) divided by (its volume)
To calculate weight from mass, you can use the formula Weight = Mass x Gravity, where Gravity is typically taken as 9.81 m/s² on Earth. This formula gives you the force exerted by gravity on an object, which is what we refer to as weight.
To calculate upthrust force, use the formula: Upthrust force = Weight of fluid displaced - Weight of object. This force is present when an object is immersed in a fluid (liquid or gas) and experiences an upward force due to the displaced fluid pushing against it.
mass/volume
The formula to calculate the weight of brass is weight = volume x density. The density of brass varies depending on the composition, but a common value is around 8.4 g/cm^3. You would need to know the volume of the brass object in order to calculate its weight.
To calculate the weight of an object under water, you can use the equation: Weight (in water) = Weight (in air) - Buoyant force. The buoyant force is equal to the weight of the water displaced by the object. By subtracting the buoyant force from the weight in air, you can find the weight of the object in water.
To calculate the density of a completely submerged object, you need to use the formula: density (ρ) = mass (m) / volume (V). If you have the volume (V) as 245.8 cubic units, you need the mass (m) of the object, which can be determined using the weight (W) and the acceleration due to gravity (g). The mass can be calculated with the formula m = W/g. If the weight is known, divide that by the acceleration (2.1) to find the mass, and then use it in the density formula.
To calculate the mass of an object, you can use a balance or scale to measure its weight in grams or kilograms. The mass of an object is the amount of matter it contains, and it is a measure of the object's inertia.
