Question

1 Explain the types of frictions with
Suitable examples?​

Answer 1

proper fraction is a fraction which has its denominator greater than the numerator, improper fraction's numerator is greater than denominator , mixed fraction have both whole and fracions, like fractions have same denominators but different numerators, unlike fractuons have different denominators and different numerators too

Explanation:

ex-

proper fraction-1/2,3/8

improper fraction-5/19,6/87

mixed fraction-1 3/43,91 572/4172

like fraction-1/4,3/4,2/4

unlike fraction-12/92 81/93

Answer 2

friction friction is a force that opposes motion between any surfaces that are in contact

Types of friction:

• Static fiction: static friction is defined as the frictional of force that acts between the surface when they are in at rest with respect to each other example: creating heat by rubbing both the hands together
• sliding friction: sliding friction is defined as the resistance that created between any two objects when there is sliding against each other example: two two cards sliding against each other in a deck
• rolling friction:rolling friction is defined as the force which resists the motion of a ball or wheel and is the weakest types of friction example: wheels of the moving vehicles
• fluid fluid friction:fluid friction is defence has friction that exists between the layers of fluid when they are moving relative to each example: the flow of ink in pens
