What formula can you use to calculate the mass of an object?
One can consider the mass of an object as a measure of how much physical “stuff” makes up that object. mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume. mass=force÷acceleration (m=F/a).
How do you calculate total weight?
Multiply the mass (in kg) by the acceleration due to gravity (in m/s/s). Your answer is in Newtons (N). For example, a 100-kg object on earth (acceleration due to gravity: 9.81 m/s/s) weighs 100 x 9.81 = 981 N.
How do you calculate your weight on Earth and moon?
On the Moon, g = 1.6 N/kg. In other words, a 1 kg mass has a weight on the Moon of 1.6 N….Summary.
| Mass | Weight |
|---|---|
| Measured in kilogrammes kg | Measured in newtons N |
| A measure of the amount of matter | The force of gravity acting on the object |
Which formula is used to calculate the mass of an object in the force and acceleration are known?
It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
How is net weight calculated?
The net weight of an item is its total weight (known as the gross weight) minus the weight of any containers or packaging the item is in (known as the tare weight). For example, the net weight of a tin of flour is the total weight minus the weight of the tin.
What weight derive the formula for calculating the weight of an object on the moon?
Answer: To find the weight on the moon, we divide the weight on earth by the earth’s force of gravity, which is 9.81m/s2. This calculates the mass of the object. Once we have the object’s mass, we can find the weight by multiplying it by the gravitational force, which it is subject to.
What is the equation that links mass and weight?
The formula is: weight/mass = gravitational field strength. On Earth the gravitational field strength is 10 N/kg.
Which formula is used to calculate the mass of an object if the force and acceleration are known m fa m?
According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a=Fm. This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.
How do you find the mass of an accelerating object?
For instance, if the object accelerates over the course of 5 seconds: 30 ÷ 5 = 6 m/s². Divide the force acting on the body by this acceleration. If, for instance, a force of 12,000 Newtons acts on it: 12,000 ÷ 6 = 2,000. This is the object’s mass, measured in kilograms.
