explain any two types of contact forces
Answers
Answer:
Contact Forces
There are different types of contact forces like normal
Force, spring force, applied force and tension force.
Normal force is when nothing is happening like a book
lying on a table because gravity is pulling it down.
Another contact force is spring force, spring force is
created by a compressed or stretched spring that could
push or pull.
Applied force is when someone is applying a force to an
object, for example a horse pulling a rope or a boy
throwing a snow ball.
Tension force is a force that is applied to a cable or a
wire. Tension force causes a force to pull equally in each
direction.
Friction
Friction is another contact force. It can be helpful and
it allows you to let you walk without sliding. The heavier
an object is the more friction it has. Friction can be
destructive for example if you rub out the mistakes you
made, the rubber become smaller and smaller.
There are 4 types of friction sliding friction, static
friction, rolling friction and fluid friction.
Sliding friction is produced when the bumps on the
surface stick together, sliding friction can also slow
down objects. Sliding friction occurs when two objects

Answer:
Types of contact force: Frictional Force: Friction is a force exerted by a surface against the motion of a body across its surface. ... Friction is a type of contact force only. Applied Force: Force which is applied to an object by another object.
