What is the weight if the mass is 70 kg?
Weight = mass*g, where g is the acceleration due to gravity. W = 70kg*9.807m/s^2 = 686.49 N (Newtons of force)
How do you convert newtons into kilograms?
kilograms is a mass and newtons is a force, but if your talking about the weight of something then you simply divide by the acceleration due to gravity (g=-9.81 m/s^2) F=ma m=F/a >>> m=W/g F: force m: mass a: acceleration W: weight A newton is actually a kg*m/s^2
What do you use to measure mass and weight?
Newton's Law F = m * a Force is a product of mass and acceleration Weight is a special case of Newton's Laws W = m * g Weight is a product of mass and the acceleration due to gravity. Weight, W, is in Newtons (N) mass, m, is in kilograms (kg) g = 9.81 m/s²
What is the gravitational force of 7 kg mass exerts on 4 kg mass?
The gravitational force between masses depends on the distance between them. > The force (and reaction) can be calculated from: : f (newtons) = (G * 7 * 4) / d2 where: G = newtons gravitational constant ( 6.672 * 10 -11) d = distance between centres of gravity in metres > Example: a distance of 0.1 metres between the masses would exert a force of on each mass of 1.868 * 10 -7 newtons
What is the weight of 20 kg on Earth?
Weight = m g = (20) (9.8) = 196 newtons (44.1 pounds)
Is express in newtons mass or weight?
Express in newtons is a measure of force, not mass or weight. It is the standard unit of force in the International System of Units (SI) and is used to quantify the amount of force applied to an object. On the other hand, mass is measured in kilograms and weight is the force of gravity acting on an object, typically measured in newtons or pounds.
How do you figure the buoyant force on an object in water in newtons?
To calculate the buoyant force on an object in water in newtons, you can use the formula: Buoyant force = weight of water displaced = V (volume of water displaced) * Ļ (density of water) * g (acceleration due to gravity). This force will be equal to the weight of the object immersed in water.
What is the difference between g and N on the balance readout?
"g" is the measure of the weight in grams and "N" is the measure of the force in Newtons.
What is the net force that acts on an object that weights 10 newtons if the object is in free fall?
The net force acting on an object in free fall is equal to the weight of the object, which in this case is 10 newtons. This is because in free fall, the only force acting on the object is gravity, which causes the object to accelerate downwards at a rate of 9.8 m/sĀ².
Why the component of weight of body is not taken in calculating the net force in banking of road?
it is, example: say g = 10, mass = 1 000 kg, then force straight down (weight) = 10 000 (newtons). horizontal force due to cornering f = m * v^2/r (newtons) draw these vectors from cog of car, resultant should be normal to road surface
What is the weight in Newtons of a 330.0 g object?
1 kilogram force = 9.807 newtons330 gram = 0.33 kg, at earths radius = 0.33 kg force, then * 9.807= 3.236 newtons
How many kilograms are in 10 newtons?
Mass is measured in kilograms and force is measured in newtons. On Earth the force F = 1 newton has roughly the mass m = 0.102 kilograms. 20 newtons are 2.04 kilograms.
What is the weight of a 10 kilogram ball using 9.8 meters per second squared?
The weight of the ball is the force exerted on it due to gravity. Using the formula weight = mass x acceleration due to gravity, the weight of a 10 kilogram ball with an acceleration due to gravity of 9.8 m/s^2 is 98 Newtons.
How can the earth and an object have the same newtons as that object?
Newtons third law by observation, action and reaction, they attract each other in equal measure. The actual force on each other (in newtons): > f = (G * mass earth * mass object) / (distance between centres of gravity)2 > (G = newtons gravitational constant 6.673 * 10-11) Bottom line: The Earth's weight on you is exactly equal to your weight on theEarth.
What are mass and weight linked by?
Weight = Mass x g g = acceleration due to gravity. (g ~= 9.8 m/s2 Weight is a Force and is calculated in newtons(N) or dynes. Mass is calculated in kilograms(kg).
If you have a mass of 90 kg and take g equals 10 meters per second squared what is the weight of this object?
Weight = m g = (90 x 10) = 900 newtons
How many newtons are on a scale of 5 newtons?
the two quantities are different - 5kg indicates the mass of the object, ie how much stuff it contains, a newton is a force, in this case a weight (a force produced by gravity, the mutual attraction of two objects with mass). The weight produced by 5kg depends on g, which is a function of how massive the other object is and how far away you are from its center. Assuming you mean 'how many newtons is 5kg on the surface of earth', g is about 9.81. To get the weight (in newtons) from the mass (in kg) all you do is multiply by g - so 5kg by 9.81 roughly equals 49 newtons. The apparent weight may be less than this. If you only want a rough estimate, then if we approximate the g from 9.81 to 10, then the force (in Newtons) is almost equal to the mass (in kg) multiplied by 10. Therefore 5kg is almost 50N (but actually less than 50). It is not accurate but it gives you an idea of the magnitude.
