What is the net force when a pair of 5-N forces simultaneously act in the same direction on an object?

Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle’s motion. It gives the particle the same acceleration as all those actual forces together as described by Newton’s second law of motion. In physics it is possible to determine the torque associated with the point of application of a net force so …

Sun Nov 11 2001 13:30:00 GMT-0500 (Eastern Standard Time) · The second law states that the rate of change of momentum of an object is directly proportional to the force applied or for an object with constant mass that the net force on an object is equal to the mass of that object multiplied by the acceleration. The third law states that when one object exerts a force on a second object that second object exerts a force that is equal in magnitude and opposite in direction on the first object .

The first law states that an object at rest will stay at rest and an object in motion will stay in motion unless acted on by a net external force .Mathematically this is equivalent to saying that if the net force on an object is zero then the velocity of the object is constant. ∑ = ⇔ = Newton’s first law is often referred to as the principle of inertia.

As described by the third of Newton’s laws of motion of classical mechanics all forces occur in pairs such that if one object exerts a force on another object then the second object exerts an equal and opposite reaction force on the first. The third law is also more generally stated as: “To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal …

In mechanics a couple is a system of forces with a resultant (a.k.a. net or sum) moment but no resultant force .. A better term is force couple or pure momen…
