F is measured in Newtons, M1 and M2 in kilograms, D in metres and constant G is equal to 6.67 x 10-11 Nm2kg-2. F can also be measured in Dynes, M1 and M2 in grams, D in centimetres and constant G is equal to 6.67 x 10E-8 Dyne. Value of the constant G was first accura...
Named after Sir Isaac Newton, the newton is defined as the force required to accelerate a one kilogram mass byone meter per second squared. It can be represented as N = kg * m/s^2. Therefore, when discussing concentrated force in SI units, we use newtons as the unit of measurement. ...
The nanonewton is a multiple of thenewton, which is theSIderived unit for force. In the metric system, "nano" is the prefix for billionths, or 10-9. Nanonewtons can be abbreviated asnN; for example, 1 nanonewton can be written as 1 nN. ...
Force, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. The concept of force is commonly explained in terms of Isaac Newton’s three laws of motion. Because force has both magnitude and direction, it is a ve
