Kinematics Glossary

Extra design capacity added to account for uncertainty.

Additional allowance for uncertainty or unexpected conditions.

a mathematical quantity that represents only magnitude, without any associated direction.

it can represent quantities such as time, temperature, mass, or distance.

A quantity that has magnitude only.

a way to express numbers that are either very large or very small in a compact and convenient format.

involves expressing a number as a product of two factors: a decimal number between 1 and 10 (known as the coefficient) and a power of 10 (known as the exponent).

The distance between two objects at a particular time.

The standard international unit used for measurement. For speed, this is metres per second (m/s).

A chosen system for representing opposite directions with positive and negative values.

Area counted as positive above the time axis and negative below it.

the digits in a number that carry meaning and contribute to its overall precision.

determined by looking at the certain digits in a number, as well as the first uncertain digit.
