What is the formula for torque?
Think about how distance, force, and angle contribute.
Define moment of inertia.
Consider how mass affects rotation.
What is torque dependent on?
Remember the formula τ = rF sin(θ).
True or False: The moment of inertia decreases as mass moves further from the axis.
Think about how mass distribution works.
A rotating disc has a moment of inertia of 2 kg·m² and rotates with an angular velocity of 3 rad/s. Calculate its angular momentum.
Remember to use the angular momentum formula.
You have two objects: one with mass concentrated at the center and another with mass distributed along the edge. Which object will require more torque to achieve the same angular acceleration?
Consider how mass distribution affects rotation.
