... The extension of a spring is directly proportional to the force causing it to stretch up to its elastic limit. The gradient of the force/extension graph up to the elastic limit is equal to the spring constant. The force applied to a spring is equal to the spring constant times the extension. The ten ...

... Definition of Apparent Weight • The apparent weight of an object is not exactly the force due to gravity acting on that object, but it is the SUPPORT FORCE acting on that object. • Remember: for an object at rest on a horizontal surface, support force and the force due to gravity are equal in magni ...

Newton`s 3rd Law
