The concept that the measurement of time and distance between events depends on the observer's frame of reference. This means that two observers moving relative to each other will disagree on the time intervals and distances measured between the same events.

A set of equations that describe how the position and time of an event are measured in two frames of reference moving at constant velocity relative to each other.

The phenomenon that a moving object's length appears shorter in the direction of motion when observed from a stationary frame of reference.

The phenomenon that time passes more slowly in a frame of reference that is moving relative to another frame of reference.

The distance between two points as measured by an observer in a frame where the two points are at rest.

The time interval between two events as measured by an observer in a frame where the two events occur at the same location.

The factor used in length contraction and time dilation that relates the measurements of distance and time in two frames of reference moving relative to each other.

A frame of reference where an object is at rest.

A physical quantity that can be measured and expressed numerically.

The standard unit for measuring a fundamental quantity.

The basic expression of a physical quantity in terms of fundamental quantities, represented by symbols like L, T, M, and K (for temperature).

Derived by combining fundamental quantities through mathematical operations, e.g., velocity, acceleration, force, work done.

The rate of change of displacement with respect to time, calculated by dividing displacement by time.

The rate of change of velocity with respect to time, calculated by dividing the change in velocity by the time taken.

A measure of the amount of heat energy transferred, represented by the symbol Q (the same symbol is unfortunately used to represent charge).

A measure of a substance's ability to absorb or release heat energy, calculated by dividing the amount of heat energy transferred by the mass and temperature change.

A vector perpendicular to the plane containing two other vectors, a and b. Its magnitude is the product of the magnitudes of a and b, and the sine of the angle between them.

The result of multiplying each component of one vector by each component of another vector. It's a mathematical tool for describing physical quantities like stress and strain.

A second-order tensor has 9 components, representing the interaction of two vectors.

A physical quantity that has both magnitude and direction. It is represented as an arrow.

A scalar quantity has only magnitude, no direction.

The sum of two vectors is a new vector whose components are the sums of the corresponding components of the original vectors.

The laws of physics remain unchanged regardless of the observer's reference frame (translation or rotation of coordinates).

The process of shifting the reference frame, such as moving the origin without changing the orientation of the axes.

The process of rotating the coordinate axes, such as rotating the reference frame without changing the origin.

Despite changes in the coordinate system (translation or rotation), the relationship between vectors remains the same.

The change in position of an object, including both the magnitude and direction.

The time interval between the start and end of a motion.

The ratio of the total distance covered to the time taken.

The speed of a particle at a specific instant in time.

A constant rate of change of velocity over time.

The area under the velocity-time graph represents the total distance covered by a particle.

The slope or gradient of the velocity-time graph gives the acceleration of the particle.

The concept that the laws of physics remain the same regardless of the observer's reference frame, even when the frame is moving with constant velocity.
