in this problem, we have been asked to explain to examples of friction from everyday life and explain why they can be described as victims. Now, friction is considered to be a victor because friction is the force of resistance between two surfaces in contact forces the victor, So friction is a victor. Now one example of this will be that pendulum which is swinging, will eventually come to rest, it will eventually stop because of friction. And this friction resist the swinging pendulum. So the direction with the pendulum is moving, the friction due to the air will move in the direction opposite to that since there is a matter of direction. Hence friction is a victor in this case. Another example is the case of a ruling ball. Football is rolling on a rough surface, then eventually it comes to a stop. This is because of friction which resists the motion. Now the friction acts in the direction opposite to the direction of motion of the ball, which is why the ball eventually stops. Here again, friction The force of friction has a direction which is opposite to the direction of the motion of the ball because it has this direction, because the direction is important in this case, hence the force of friction is once again acting as a vector in this case. So two examples of friction from everyday life are a pendulum, which comes to a stop eventually due to friction due to the air, and a rolling ball, which comes to a stop eventually due to the friction between the ball and the surface on which it is rolling. And in both cases the friction resists the motion. It acts in the direction opposite to the motion, and hence because of this direction, her friction can be considered as a victor.
