Frictional force is significant in everyday life because it allows us to walk, grip objects, drive cars, and stop moving objects. Without friction, it would be challenging to perform these tasks as objects would be uncontrollable and slide uncontrollably. Additionally, friction is essential for the operation of many machines and tools we use daily.

What are three energy sources that you use every day?
It can affect in the following ways:- Forward force that we apply to make a motion. Frictional force acts automatically even when we make slightest move. Gravitational force that keeps us from flying up in the sky.
How are force and motion part of your everyday life?
Force and motion are part of everyday life in various ways, such as when walking, driving a car, or even sitting still. Force is needed to accelerate or decelerate objects, while motion occurs when there is a change in an object's position relative to a reference point. Examples include pushing a door open (applying force) or riding a bike (experiencing motion).
What is the difference between mechanical advantage and Efficiency?
Mechanical advantage refers to the ratio of output force to input force in a simple machine or system. Efficiency, on the other hand, is a measure of how well energy is converted from input to useful output. Mechanical advantage focuses on force ratios, while efficiency assesses energy losses.
When friction seems to retard motion?
Friction is a force that opposes the motion of objects sliding against each other. When friction appears to slow down the motion of an object, it is because the frictional force is acting in the opposite direction of the object's motion, reducing its speed. This can be observed in everyday situations like when trying to push a heavy box across the floor.
How would the life of human beings be if there was no frictional force?
If there was no frictional force, human beings would have difficulty walking, running, or even standing still, as there would be no traction between our feet and the ground. Driving vehicles would be nearly impossible, and objects would slide around uncontrollably. Many everyday tasks and activities would be challenging without friction to provide stability and grip.
