1. Explain the difference between heat and temperature.

2. Describe the direction of thermal energy in objects of different temperatures.

3. What happens when thermal equillibrium is reached (all objects have the same temperature)?

Using software, a simulation of a javelin being thrown both on earth and on the moon is created. in both cases, the velocity and angle of projection are kept the same. on earth, the javelin covers a distance y. what distance would it cover on the moon? (the moon’s gravity is about 1/6th that of earth.) a. 6y b. 6/y c. y/6 d. (y+6)2
