Force
Non-contact
What is a non-contact force?
A non-contact force is a force applied to an object by another body that is not in direct contact with it. Non-contact forces come into play when objects do not have physical contact between them or when a force is applied without any interaction.
Types of non contact force:
Gravitational force.
example:the Earth pulling on you and keeping you on the ground.
Magnetic force.
Magnets attract, or pull, objects made with iron.
Paper clips, scissors, screws, nuts, and bolts are just a few common everyday objects that are magnetic. A magnet will not attract paper, rubber, wood, or plastic. It is not true that a magnet will attract any kind of metal.
Electrostatics.
Examples: The attraction of paper to a charged scale by rubbing to hair.
Nuclear force.
Nuclear force is the force between nucleons. It is the force that pulls protons and neutrons into atoms.
Contact
What is contact force?
Contact forces are forces in which two or more objects or bodies touch or contact each other directly.
Types of contact force:
Reaction force. An object at rest on a surface experiences reaction force . .
For example, consider the interaction between a baseball bat and a baseball. The baseball forces the bat to the left; the bat forces the ball to the right. Together, these two forces exerted upon two different objects form the action-reaction force pair.
Tension. An object that is being stretched experiences a tension force.
Example: Pulling a string and then letting it go. When you let it go, it goes back to its original position in a snap.
Friction. Two objects sliding past each other experience friction forces
For example:you would have to push a book harder to get it moving on a carpet than you would on a wooden floor.
Air resistance. An object moving through the air experiences air resistance .
when an aeroplane flies through the air, air particles hit the aeroplane making it more difficult for it to move through the air. It's the same for an object moving through water.
