Learning Objectives

6.5.1.2 Contact and non-contact forces

Content	Key opportunities for skills development
$A force is a push or pull that acts on an object due to the interaction with another object. All forces between objects are either: contact forces - the objects are physically touching non-contact forces - the objects are physically separated. Examples of contact forces include friction, air resistance, tension and normal contact force. Examples of non-contact forces are gravitational force, electrostatic force and magnetic force. Force is a vector quantity. Students should be able to describe the interaction between pairs of objects which produce a force on each object. The forces to be represented as vectors.$
