Contact & Non-Contact Forces
This lesson covers:
1What we mean by 'contact' and 'non-contact' forces
2Examples of contact and non-contact forces
A force is a push or that acts upon an o as a result of that object's interactions with its surroundings.
|
Force is measured in (N), and has both a m and a d.
Therefore, force is a vector quantity.
|

A non-contact force can be exerted without objects physically touching
A contact force can only be exerted when objects are physically touching
