ForcesIn science, a force is a push or pull that acts on an object. Forces are part of our everyday lives. Without forces, many tasks that we can currently perform easily, would be almost impossible. Forces have the ability to move objects or stop them from moving.
Classifying Forces
All forces are classifyed as either a contact force or an action-at-a-distance force. For more information on classifying forces, click here.
Weight vs Mass: What's the Difference? Many times, people become confused between the mass and weight of an object. For more information on Weight vs Mass, click here. How to Measure Forces
The metric unit of force is the Newton (N), named after Sir Isaac Newton. Since WEIGHT is the same as the Force of Gravity, it is measured in Newtons. On Earth, something with a 1.0 kg mass has a weight of 9.8 N. When we "weigh" something, for example, at the grocery store, the scale is usually maked in kilograms. Therefore, we are NOT find the weight (in N), but rather we are finding the mass (in kg).
