Friction Friction – a force that opposes motion between 2 surfaces that are touching. –Always acts in a direction opposite to the motion of the object.

Presentation transcript:

Friction Friction – a force that opposes motion between 2 surfaces that are touching. –Always acts in a direction opposite to the motion of the object. –The greater the friction, the faster an object will lose speed. FRICTION

TYPES OF FRICTION EXPLANATION SlidingA hockey puck crossing an ice rink RollingA wheeled cart being pushed FluidAir rushing past a speeding car StaticA crate resting on a loading ramp

Energy of Motion Kinetic Energy – Energy in a moving object. –More speed or more mass = more kinetic energy Potential Energy – Energy stored in an object because of position –High diver on the board – lots of potential energy –Becomes kinetic energy when he dives!

Mass vs. Weight Mass = amount of matter in an object Weight = force of gravity on an object –NOT THE SAME THING!!! –Weight = gravity x mass On Earth Weight = 120 lbs Mass = kg On the Moon Weight = 20 lbs Mass = kg In Space Weight = 0 lbs Mass = kg
