You go grab a car door handle in the summer (energy transfer to heat up the handle conduction) and it burns you through energy transfer.
A. Radiation-transfer of energy (heat) through space by electromagnetic rays.
B. Conduction-the transfer of energy (heat) through the matter by molecules energy (touch).
C. Convection-the transfer of heat movement of mass or substance (motion).

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
