b. potential energy

c. kinetic energy

d. total mechanical energy

1. The term acceleration was used in paragraphs 1-3. Which of the following could be a definition of acceleration? A. A change in an object's speed B. At object at rest C. A change in an object's direction D. Both A and C

If an atom has 3 protons, 3 neutrons, and 2 electrons, what is the electrical charge of the atom?

Which statement is most clearly objective? a. according to hernandez, i believe pilots must retire in their 60s. b. walters argues that no american in society is truly an island. c. the strongest aspect of cunningham's argument is the research. d.

Kinetic energy is defined as ½ mv2, where m is the mass of the object, and v is the velocity (or speed). Two gas molecules have the same kinetic energy, but molecule X has four times the mass of molecule Y. What can you say about their speeds?
