Inclined Plane Activity

We choose a small angle for the inclined plane, such as 20 degrees, so that when we compute the component forces, the larger component force will be the normal force going into the ground and the smaller force will be moving the sled down the frictionless inclined plane.

sin \theta = \dfrac {m g_i} {mg} = \dfrac {g_i} {g}

g_i = sin \theta g
