Mass is defined as the amount of matter in an object while weight is defined as the force exerted by an object. SI unit of mass is kilograms while SI unit of weight is Newtons. Object weighing 1 kg mass will have 9.8 N weight.
An object with a mass of 37 g displaces 497 ml of water when it's completely immersed. What is the buoyant force on the mass? Answer in Newtons (N) to one decimal place, acceleration due to gravity = 9.8 N/kg. An object with a mass of 82.0 g displaces 570.0 ml of water when ...

One Newton equals about 100 g on Earth. How many Newtons would a football weigh if it has a mass of 400 g? How does acceleration depend on mass? How does Newton's law of inertia describe the motion of objects? A spring is 2 kg, has a constant of 80 Newton/meter, and stretches 0....
Acoustical Systems: Inputs in Q (Volume Acceleration) and outputs in Sound Pressure (Pascals) Combined Acoustic and Mechanical systems: Inputs in force (either Q or Newtons) and outputs in Sound Pressure (Pa), Acceleration (g's), etc Rotational Mechanical Systems: Inputs in Torque (Nm) and...
The actual determination of weight might be better calculated with special consideration for the local acceleration of gravity based on altitude or latitude. Adjustments for altitude, latitude and the Earth’s radius can be factored in to show how an object will weigh more at higher latitudes than...
