The SI unit of force is the newton (symbol N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared, or kg·m·s −2.The corresponding CGS unit is the dyne, the force required to accelerate a one gram mass by one centimeter per second squared, or g·cm·s −2. A newton is thus equal to ...
In military science, force multiplication or a force multiplier is a factor or a combination of factors that gives personnel or weapons (or other hardware) ...
In the first case the force is continuously applied to the car by a person, while in the second case the force is delivered in a short impulse. Contact forces are often decomposed into orthogonal components, one perpendicular to the surface(s) in contact called the normal force, and one parallel to the surface(s) in contact, called the friction ...
The apparent outward force that draws a rotating body away from the centre of rotation. It is caused by the inertia of the body as the body's path is continually redirected. centripetal force A force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre. cGh physics
Force – an influence that can push or pull an object to change its motion. A force can cause an object with mass to change its velocity (e.g. moving from a state of rest), i.e., to accelerate. A force has both magnitude and direction, making it a vector quantity. Force density – Forging – Four-bar linkage – Four-stroke cycle – Four ...

The work W done by a constant force of magnitude F on a point that moves a displacement s in a straight line in the direction of the force is the product = For example, if a force of 10 newtons (F = 10 N) acts along a point that travels 2 metres (s = 2 m), then W = Fs = (10 N) (2 m) = 20 J. This is approximately the work done lifting a 1 kg ...
