What is the effect of increasing the distance from the axis of rotation when applying a force?
The torque increases.
What happens when the net torque on an object is zero?
The object is in rotational equilibrium.
What happens when an object converts more potential energy into rotational kinetic energy?
The object will reach the bottom of the ramp faster.
What are the differences between rolling and sliding?
Rolling: Object rotates and translates without slipping (friction does no work). Sliding: Object translates without rotating (friction does work).
Compare a frictionless ramp vs. a ramp with friction in the context of objects rolling down.
Frictionless Ramp: All objects reach the bottom at the same time. Ramp with Friction: Objects arrive in order: ball, hoop, then box.
What are the steps to draw a rigid body diagram?
- Identify the object and its reference frame. 2. Draw the forces acting on the object as vectors. 3. Draw the moments (torques) acting on the object as vectors. 4. Label all vectors with their magnitude and direction. 5. Sum the forces and moments to find the net force and net moment.
