F mg physic
WebDec 23, 2024 · F = mg = (250 kg)(9.8 m/s 2) = 2,450 N. where F equals force, m equals the mass of the object, and g equals the acceleration due to gravity, 9.8 meters per second 2. In order to figure out how to calculate the spring constant, we must remember what Hooke’s law says: F = –kx. Now, we need to rework the equation so that we are calculating for ... WebThe weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. For an object in free fall, so that gravity is the only force acting on it, then the expression for weight follows from Newton's second law.
