Mathematical Equation For Force

A force has both magnitude and direction making it a vector quantity.

Mathematical equation for force. The classical equation for force is one of the most important equations in physics. Bold f net bold f 1 f 2 f 3. Osipov independently devised a series of. The net force fnet acting upon an object moving in circular motion is directed inwards.

The equation on the right above is derived from the equation on the left by the substitution of the expression for speed. The general formula for work and for determining the amount of work that is done on an object is. When you ve solved the equation the force will be measured in newtons. Now simply plug the values you know into the equation and solve.

Force can also be described as a pull or push. The net force is the vector sum of all forces acting on a body. Lanchester s laws are mathematical formulae for calculating the relative strengths of military forces the lanchester equations are differential equations describing the time dependence of two armies strengths a and b as a function of time with the function depending only on a and b. Mathematically the force equation is.

As above with p and q vector a is in the same direction as vector f. Mass is a scalar and acceleration is a vector. Force is an interaction between two objects which causes a change in object motion. F m a.

If you have any two of the three variables you can solve for the third. The force equation is a simple formula that captures the relation between the physical quantities of force mass and acceleration and how changes in these quantities cause changes in the others. Typically it causes an object with mass to accelerate or decelerate. Acceleration is a change in velocity.

The amount of work a force does is directly proportional to how far that force moves an object. Force can also be described intuitively as a push or a pull. It is measured in the si unit of newtons and represented by the symbol f. In other words work is equivalent to the application of a force over a distance.

Recall that a force is a push or a pull the si unit for force is the newton n where 1 n 1 kgm s 2. In 1916 during world war i frederick lanchester and m. This multiplication yields a vector that is called the force vector or f which is on the left side of the equation. Make sure that the mass measurement you re using is in kilograms and the acceleration is in meters over seconds squared.

While there may by more than one force acting upon the object the vector sum of all of them should add up to the net force. So the right side of this equation is a scalar times a vector. A force can cause an object with mass to change its velocity which includes to begin moving from a state of rest i e to accelerate. It is a vector quantity with a direction and magnitude.
