A gnathodynamometer (or occlusometer) is an instrument for measuring the force exerted in closing the mouth. This device can measure the bite force of humans in the following three measurements: newtons, (N), pounds, (lb), or kilograms, (kg). The average bite force of a human being is 140 pounds of force.
The jaw elevator muscles develop the main forces used in mastication. The force generated during routine mastication of food such as carrots or meat is about 70 to 150 newtons (16 to 34 lbf). The maximum masticatory force in some people may reach up to 500 to 700 newtons (110 to 160 lbf). [1]: 156
Bite force quotient (BFQ) is a numerical value commonly used to represent the bite force of an animal adjusted for its body mass, while also taking factors like the allometry effects. The BFQ is calculated as the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms. [ 1 ]
Human bite mark. Criminally, Forensic Dentistry is involved in bite-mark analysis. Because bite-marks change significantly over time, investigators must call for an expert as soon as possible. Bites are then analyzed to determine whether the biter was human, self-inflicted or not, and whether DNA was left behind from the

In physics, a body force is a force that acts throughout the volume of a body. [1] Forces due to gravity , electric fields and magnetic fields are examples of body forces. Body forces contrast with contact forces or surface forces which are exerted to the surface of an object.
