Define force and Friction. Write their types with examples.
Answers
Answer:
Force:-
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
There are many examples of forces in our everyday lives:-
weight force (i.e. the weight of something)
the force of a bat on the ball.
the force of the hair brush on hair when it is being brushed.
the force of your foot pushing on the pedal when you ride your bike.
Friction:-
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism.
examples of friction:-
There are different types of friction.
A book moving across the desk is an example of sliding friction.
Air resistance is a type of fluid friction.
As an object falls, air resistance pushes up on the object. When you ride a bicycle, the contact between the wheel and the road is an example of rolling friction.
