Acceleration is the rate at which the velocity vector changes

Charges are the basis of electricity. A charge exert forces on other charges. The smallest charge is the charge of an electron, 0.000000000000000016 Coulombs.

Current is the rate of flow of electrical charge.

One of the undefined qualities of physics, it measures the separation of two points.

Dependent Variable
When two variables are related, we say that one depends on the other. This variable is called the dependent variable. The"other" variable is free to roam so it is called the independent variable. In a scientific experiment, the experimenter chooses values for the independent variable, runs the experiment, and measures the dependent variable. Ordered pairs of choosen and measured values (independent and dependent) are often plotted on a two dimensional graph for visualization. The dependent variable is traditionally plotted on the vertical axis.

The energy of an object increases when work is done on it. An increase in energy may heat up the object, speed it up, lift it up, or all of the above.

The strength of a force is defined by the rate at which it can speed up one kilogram of mass.

Independent variable
When two variables are related, one of the variable is free to roam so it is called the independent variable. The other variable depends on the first, so it gets the name dependent. In a scientific experiment, the experimenter chooses values for the independent variable, runs the experiment, and then measures the dependent variable. Ordered pairs of choosen and measured values (independent and dependent) are often plotted on a two dimensional graph for visualization. The independent variable is traditionally plotted on the horizontal axis.

Notice that this energy of motion is proportional to the square of the speed. The unit of Joule may also be expressed as kg(m/sec)(m/sec).
