Normal Force on an Inclined Plane (Ramp)

0:00 Learning Goals 0:30 Increases, no change, decreases 1:25 Data table 1:49 Experiment set-up 2:11 Mass as inclination angle increases 5:35 Scales measure NORMAL force 6:12 Force diagram 6:45 Forces in equilibrium 7:37 Why cosine? 8:34 Deriving m0cos(theta) = m 9:29 Less normal force means less friction What do balances actually measure? Is it the force of gravity or the normal (support) force? How does the mass as registered by a scale change if the scale is placed on an inclined plane? This video explores these questions and more. Learn about the normal force through a demonstration experiment. The normal force and its relation to gravity (weight) is explored in detail. Finally, the consequences of normal force decreasing on an inclined plane are examined in terms of friction.
