Classify:Energyis the ability to exert force and cause change. Energy has manyforms:
• Kinetic energyis energy of motion. All moving things have kinetic energy.
o Soundis energy of vibrating materials or air molecules.
o Thermal energyis the energy of tiny moving particles. As an object heatsup, particles move faster and thermal energy increases.
• Gravitational potential energyis stored energy that exists based on theposition of an object. The higher an object is, the greater its gravitational potentialenergy.
• Electrical currentis energy that comes from moving charged particles.
• Lightis electromagnetic waves that are visible to the eye.
• Chemical energyis energy that is stored in the bonds holding atoms together.
• Nuclear energyis energy released when atoms split apart or join together.

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
