What type of kinetic energy does a box sliding down a frictionless incline have?
How can you ensure not to double-count kinetic energy in a system with both linear and rotational motion?
A disk has a mass of 5 kg and a radius of 0.4 m. If it spins at an angular velocity of 10 rad/s, calculate its rotational kinetic energy.
A solid sphere of mass 2 kg is rolling without slipping at a linear velocity of 3 m/s. Calculate its total kinetic energy.
What happens to the linear kinetic energy of a rotating object when its angular speed is doubled?
