Contact and Non-Contact Forces
Contact and Non-Contact Forces
Forces can also be classified based on whether they come into contact with the object they are acting on or not.
A contact force is a force that touches the object it is acting on.
Most forces are contact forces.
We will discuss three special types of contact forces โ friction, buoyancy and surface tension โ in a later lesson.
A non-contact force is a force that does not touch the object it is acting on - they act at a distance. Instead of touching an object, non-contact forces act through a force field.
There are only a few types of non-contact forces.
We will discuss three types of non-contact forces โ gravity, magnetism and electrostatic forces โ below.
