Kinetic energy is the energy the body possesses due to its motion. Kinetic energy is a kind of mechanical energy, as well as potential energy. All bodies that move linearly or rotate possess a certain kinetic energy.
Potential energy is the energy that an object has due to its position relative to another object. When we stand on the top of the building, we have more potential energy than when we are at the bottom, because the earth is attracted by the force of gravity.
When the body falls, it at the beginning of the fall has potential energy due to the force of gravity, and therefore falls, and then the potential energy turns into a kinetic, because the body moves in the fall.
When we kick the ball upwards, it moves upward, because it has kinetic energy, until it stops at one point, since there is no kinetic energy of motion, and only at that moment the kinetic energy turns into a potential, at that moment the ball is stopped, until it starts to fall again.
Correct answers are II. and III.

Answer: The following is one of the friendship rules identified in a study by communication researchers Michael Argyle and Monika Henderson:
B. Don't be jealous of your friend's other friends.
Explanation:
Michael Argyle and Monika Henderson conducted a study and were able to identify rules for successful friendship, one of those rules was, "Don't be jealous of your friend's other friends."
In "The Rules of Friendship" Journal of Social and Personal Relationships (1984), Argyle and Henderson found some of the following 'rules', "...“should not be jealous of other’s relationships,” “help in time of need,” “respect the friend’s privacy,” “confide in each other,” and “stand up for the other person in their absence."
Extraneous
An <em>extraneous variable</em> is a variable in an experiment that you are not intentionally studying. These variables usually provide undesired affects on the experiment.
In this example, the independent variable is whether a sentence is humorous or not, and the dependent variable is the memory performance score. However, because the humorous sentences are only given to males, and the non-humorous sentences are only given to females, gender becomes an extraneous variable as you are not intentionally testing gender's relation to the dependent variable, but it is still affecting the experiment.
