Object 1 starts at 5.4 m and moves with a velocity of 1.5 m/s. Object 2 starts at 8.1 m and moves with a velocity of -2.2 m/s. The two objects are moving directly toward one another. The object with the greater

speed is Object

(ONLY WRITE THE NUMBER 1 OR 2 IN

THE RESPONSE BLANK). The two objects will collide at

the results is a decrease in air temperature with an increase of altitude.

explanation:

pe = weightxheight = 2000x1000=2,000,000joules

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
