Physics Concepts

Front

Acceleration

Back

The rate at which an object's velocity changes with time; the change in velocity may be in magnitude (speed), or direction, or both.

Front

Acceleration due to Gravity

Back

The acceleration of a freely falling object. Its value near Earth's surface is about 9.8 m/s² (~9.8 m/s each second).

Front

Air Resistance

Back

Friction, or drag, that acts on something moving through air.

Front

Average Speed

Back

Path distance divided by time interval.

Front

Biology

Back

The study of life and living organisms.

Front

The branch of science that focuses on properties, composition, and structure of matter.

Back

Chemistry

Front

The Greek letter “delta” (Δ) is used to represent a change or difference in a particular quantity.

Back

Δx (change in x) or ΔT (change in temperature)

Front

The total path length, often measured in units such as meters, kilometers, or miles.

Back

Distance

Front

When the net force acting on an object is zero and the object is moving at constant velocity.

Back

Equilibrium

Front

Elapsed time is the total amount of time that has passed from the start of an event to its end.
