MAKING WORK EASIER FRICTION

• friction is the force that opposes motion.
• it moves in the opposite direction.

ADVANTAGES OF FRICTION

• skating
• walking
• writing
• erasing
• braking
• sharpening
• griding

DISADVANTAGES OF FRICTION

• Causes wearing out of things Makes work difficult Produces unwanted heat
• Hinders motion
