There are many substances that are toxic in large amounts, but are vital for human health. One of these is cobalt.
Scalar quantities are measurements which have no specific physical direction. Two fundamental scalar quantities are mass and time. Mass and time simply exist without any directionality whatsoever. By way of comparison, distance is a fundamental vector quantity and not a scalar quantity. You cannot travel any distance without going in a specific physical direction: up or down, left or right, north or south, forward or backward, etc.
A meaurement; a scalar quantity.
Length, mass, volume, temperature, density, and energy are all examples of scalar quantities.
Speed is an example of a scalar quantity, as it only has magnitude (numerical value) without a specific direction.
Here are some examples:* energy * power * mass
scalar measurements differ from vector measurements in that scalar measurements have no directionality. Example: If a car travels in a circle with a circumference of 25m it will have travelled: distance (scalar): 25 m displacement (vector): 0m
A scalar is just a number. A vector is a row or column of numbers. For example: 6 is a scalar while (1, 0, 23.5) is a vector.
Yes. Speed is the rate of change of distance. Distance and time being scalars, SPEED is also a scalar
Temperature is a scalar quantity. It has magnitude but not direction.
Not at all. Scalar are numerical quantities without direction (for example time) where as vectors are numerical quantities with direction (for example gravitational force downward)
A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a scalar; force is usually indicated as a vector (magnitude in Newton, but the direction is also relevant).A scalar quantity is a non-vector quantity.
