The direction towards which the force is applied is known as the direction of the force and the application of force is the point where force is applied. For simplicity sake, all forces (interactions) between objects can be placed into two broad categories: 1. contact forces, and 2. forces resulting from action-at-a-distanceContact forces are those types of forces that result when the two interacting objects are perceived to be physically contacting each other. To put that in perspective, about half of one of Isaac Newton's apples would exert 1 N of force. Examples of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces. SI prefixes represent multiples of 103 or 10‑3. 1 Pa = 1N/m 2 For … Define the SI unit of force, the newton; Describe force as a vector; The study of motion is called kinematics, but kinematics only describes the way objects move—their velocity and their acceleration.

Derive a relation between newton and dyne. Historically, there have been a variety of units of force and conversion factors. What does force per unit area mean? The SI unit is ‘pascals (Pa)’. Force, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. In the 20th century, people needed a more precise definition. 1 Pa = 1N/m 2 Force definition, physical power or strength possessed by a living being: He used all his force in opening the window. In other words, a kilogram mass exerts about 9.8 newtons of force. If an electric force of one unit (one dyne) arises between two equal electric charges one centimetre apart in a vacuum, the amount of each charge is one electrostatic unit, esu , or statcoulomb.
