Friction

Master friction! Match definitions and identify static, sliding, rolling, and fluid friction in fun examples.

Match the type of friction with the correct definition. Static friction A frictional force that acts on objects that are not moving Sliding friction a force that opposes the motion of an object sliding over a surface Rolling friction a force that opposes the motion of rolling objects Fluid friction a force that opposes the force of an object moving through a fluid What type of friction is most likely impacting a Tesla driving down the highway? static friction sliding friction rolling friction fluid friction What type of friction is most likely impacting a car parked on a steep hill? static friction sliding friction rolling friction fluid friction What type of friction is most likely impacting the skier skiing down a hill? static friction sliding friction rolling friction fluid friction What type of friction is most likely impacting a swimmer competing in a 100 meter freestyle race? static friction sliding friction rolling friction fluid friction What type of friction is most likely impacting a child going down a playground slide? static friction sliding friction rolling friction fluid friction What type of friction is most likely a zorb rolling down a hill? (Note: a zorb is an inflatable "hamster" ball for humans). static friction sliding friction rolling friction fluid friction What type of friction is most likely impacting a skydiver hurtling towards the ground? static friction sliding friction rolling friction fluid friction What type of friction is most likely impacting a boulder precariously perched upon a precipice? static friction sliding friction rolling friction fluid friction
