In physics, a body force is a force that acts throughout the volume of a body. 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. Normal forces and shear forces between objects are … See more Qualitative A body force is simply a type of force, and so it has the same dimensions as force, [M][L][T] . However, it is often convenient to talk about a body force in terms of either the See more • Action at a distance • Fictitious force • Force density • Non-contact force • Normal force • Surface force See more Like any other force, a body force will cause an object to accelerate. For a non-rigid object, Newton's second law applied to a small volume element is See more In the case of a body in the gravitational field on a planet surface, a(r) is nearly constant (g) and uniform. Near the Earth $${\displaystyle g=9.81{\frac {\mathrm {m} }{\mathrm {s} ^{2}}}}$$ See more WebForce is a vector quantity that is measured in Newtons (N) or pounds (lb).
