Practicing Success
A drum of radius R and mass M, rolls down without slipping along an inclined plane of angle θ. The frictional force: |
Decreases the rotational and translational motion Dissipates energy as heat Decreases the rotational motion Converts translational energy to rotational energy |
Converts translational energy to rotational energy |
The gravitational potential energy decreases and the translational energy is converted into the the rotational form of energy. The frictional force applied torque which causes angular acceleration. Angular acceleration increases angular velocity and hence rotational energy. |
