is magnitude the same as force?

In general, an object can be acted on by several forces at the same time. A force is a vector quantity which means that it has both a magnitude and a direction associated with it. Two forces with the same magnitude but different directions are not equal forces.

Why is work a scalar quantity although force and displacement are vector quantities?(Answers apart from work has magnitude but no direction).

If there is just one force on an object, then that force is the net force. ... For example in free fall, the net force on an object equals its weight - the one force pulling on it. If 2 forces push or pull on an object in opposite directions, and the two forces cancel each other exactly, the net force is zero.

Either force can be considered the action force or the reaction force. You might think that because action-reaction forces are equal and opposite that they cancel. However, action and reaction force pairs don't cancel because they act on different objects. Forces can cancel only if they act on the same object.

Momentum is mass times velocity. So force is the change in (mass times velocity) with respect to time: F = d(mv)/dt. In most situations we figure mass is constant. So force is proportional to a change in velocity.

magnitude. The magnitude is a number that characterizes the relative size of an earthquake. ... The moment magnitude (Mw) scale, based on the concept of seismic moment, is uniformly applicable to all sizes of earthquakes but is more difficult to compute than the other types.

In symbols, the magnitude of the attractive force F is equal to G (the gravitational constant, a number the size of which depends on the system of units used and which is a universal constant) multiplied by the product of the masses (m1 and m2) and divided by the square of the distance R: F = G(m1m2)/R2.

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This verbal statement can be expressed in equation form as follows: a = Fnet / m.

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. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Weight is a measure of the force of gravity acting on an object. According to Newton's laws of motion, force is directly proportional to both mass and acceleration, and the equation for force is F = m * a, where m = mass and a = acceleration. We can use this equation to solve for weight.

vector function has both quantities magnitude and direction whereas scalar has only one quantity which is magnitude. ... scalars have magnitude but no direction.

The formula for force says force is equal to mass (m) multiplied by acceleration (a). If you have any two of the three variables, you can solve for the third. Force is measured in Newtons (N), mass in kilograms (kg), and acceleration in meters per second squared ( m/s2 ).

Force is defined as a push or pull on an object resulting from the object's interaction with another object. Displacement is the distance and direction an object is moved. Force and work are directly proportional to each other, while force and displacement are indirectly propotional.

Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element. Force and power can both be described and measured, but a force is an actual physical phenomenon, and power in itself is not.

The two quantities are equal when the motion occurs without any change in direction. In that case, the individual displacements point in the same direction, so the magnitude of the net displacement is equal to the sum of the magnitudes of the individual displacements (the total distance).

So force is the change in (mass times velocity) with respect to time: F = d(mv)/dt. In most situations we figure mass is constant. So force is proportional to a change in velocity. (F = m dv/dt, or mass times acceleration.)

Force is mass times acceleration, or F= m x a. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass. This is Newton's Second Law of Motion.
