what is force?????????
Answers
In physics, a force is any influence that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
Units
The unit is newton per square meter (N/m^2), kilogram (force) per square centimeter (kg/cm^2) or pascal. Most commonly used unit of strength is pascal, which is defined as force of 1N that is exerted on unit area.
Sum
The vector sum of all of the forces acting on a body is a single force called the net force . ... Because there is no net force acting on an object in equilibrium, then from Newton's first law of motion, the object continues to move at a constant speed.
