Contact and Non-Contact Forces

force

is a concept that describes the interaction between two objects that can change the motion of one or both of them

• move

• stop

• change direction

force is a push or pull that can cause an objec to

CONTACT FORCE

It is a force that requires contact on both objects to occur.

CONTACT FORCE

Force between two bodies that are in direct contact with each other.

TYPES OF CONTACT FORCES

• normal force

• tensional force

• frictional force

• air resistance/drag force

normal force

A force is exerted against the gravitational force present by objects touching each other.

tensional force

A force applied to a rope, string or cable that makes them to be compressed or to be stretched by pulling on each side.

frictional force

A force created by both surfaces of the objects that is being rubbed against each other resulting by moving in either same direction or different direction.

air resistance/drag force

A force in the opposite direction of object in air or fluid.

non-contact forces

Action at a distance forces is the other term for non-contact force and only results when two objects interact without any physical contact with each other.

non-contact forces

Regardless of their physical separation they can exert push or pull to the object.

types of non-contact forces

• magnetic force

• electrostatic force

• gravitational force

magnetic force

Attraction and repulsion resulted by putting together the end of same poles or different poles of the magnetic object.

electrostatic force

Just like magnetic force, is either attractive or repulsive resulted by positive and negative charges of particles.

gravitational force

Pulling of objects with masses towards the center of the Earth.
