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)
