## How the forces on body are measured?

In the SI system, the magnitude of a force is measured in units called **newtons**, and in pounds in the British/American system. If a body is in motion, the energy of that motion can be quantified as the momentum of the object, the product of its mass and its velocity.

## How do you calculate the force between two bodies?

**F=Gm1m2r2 , where:**

- F = gravitational force ( N )
- G = gravitational constant ( ~6.67⋅10−11Nm2kg−2.
- m1 and m2 = masses of objects 1 and 2 ( kg )
- r = the distance the centre of gravities of both objects ( m )

## How is push force measured?

When measuring push or pull force, you must use **a force gauge**. The technique requires positioning the gauge (force) parallel to the ground and applying a steady push or pull.

## How do you calculate the force of attraction between ions?

Ions exhibit attractive forces for ions of opposite charge — hence the adage that “opposites attract.” The force of attraction between oppositely charged ions follows Coulomb’s law: **F = k * q _{1} * q_{2} / d^{2}**, where F represents the force of attraction in Newtons, q

_{1}and q

_{2}represents the charges of the two ions in coulombs …

## How much force can a human pull?

The force which a man exerts in dragging a load has been variously estimated. Schulze ays that a man can exert a pressure of 107 lbs. for a short time, and that a man may walk at the rate of from **4 to CJ miles per hour**.
