... Problem 12.18. A 2.00 kg object is attached to a spring and placed on a horizontal, smooth surface. A horizontal force of 20.0 N is required to hold the object at rest when it is pulled 0.200 m from its equilibrium position (the origin of the x axis). The object is now released from rest with an in ...

Forces
... In a nutshell: Law 1: An object’s velocity doesn’t change unless acted upon by a net force. Law 2: The acceleration of an object upon which a force is acting depends on the amount of net force being applied and on the mass of the object. Law 3: For every force, there is an equal and opposite ...
