Referring to the figure, the _____ energy of the skateboarder at point (i) is converted to _____ energy when he momentarily comes to rest at (f).  

A pendulum has 30 J of gravitational potential energy when it is released from rest. At a later time, its gravitational potential energy is 12 J. If you ignore friction, the pendulum must have _____ of kinetic energy at that instant.

A 72-kg bungee jumper plummets 54 m straight downward from a bridge. How much gravitational potential energy does she lose?

Work is one way of transferring energy to an object.

A hamburger’s energy content of 419,000 cal is equivalent to 100,000 J.

The Celsius temperature scale is defined such that molecular motion is at a minimum at zero degrees (0 °C).

While a gas is being compressed, 50 J of work is done on the gas while its thermal (internal) energy decreases by 30 J. We conclude that

D. (7 pts) The heat engine in a chain saw has an efficiency of [ef] and performs [W] kJ of work. How many milliliters (mL) of gasoline does the chain saw burn if gasoline has an energy content of 34.6 kJ/mL? {Enter the value (not the units) in the box below.
