An example using a car:
Advantage: friction on car tires makes the car stop. Without friction, the car would continue without stopping (e.g. such as mass in space once given a push in one direction)
Disadvantage: friction on car tires means more energy is required to propel the car forward = more gas is required for a trip.

Advantages of friction: It allows us to walk without slipping, helps stop moving objects, and provides grip for vehicles on roads. Disadvantages of friction: It causes wear and tear on surfaces, reduces efficiency in machines, and can generate heat leading to energy loss.
These are a few of the great many advantages and disadvantages of having friction in sport: Friction allows a running person to stop, change direction, jump, catch a ball, and throw a ball. Friction between a ball and the air limits how far it can be thrown (although gravity has an even greater effect). Runners require energy to overcome the friction between their feet and the ground.
1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.
Advantages of linear motion include simplicity, precision, and ease of control. Disadvantages may include limited speed compared to rotary motion, higher friction and wear on components, and potential for misalignment.
