... An object that is at rest will remain at rest and an object that is moving will continue to move in a straight line with constant speed, if and only if the sum of the forces acting on that object is zero. Newton's 2nd Law acceleration of an object = sum of forces acting on that object / the mass of ...

... This will be the sum of the forces. Force of gravity is always present(mass x 9.8 N/kg), which will be the force pushing down on the surface, so the force the 75 kg mass “feels” is the equal but opposite force pushing back up from the surface (Normal force). If the elevator was accelerating up, that ...
