Which quantity is scalar
A scalar quantity is a physical quantity that can be fully described by its magnitude or size alone. Examples of scalar quantities include temperature, speed, mass, and time.
A scalar quantity is a physical quantity that has magnitude only. It does not have a direction associated with it. Examples of scalar quantities include mass, temperature, time, and distance.
A scalar quantity is a physical quantity that has only magnitude and no direction. Scalar quantities are fully described by their magnitude or numerical value. Some examples of scalar quantities include mass, temperature, time, speed, and energy.
To determine if a quantity is scalar, you can consider whether it has a direction associated with it. If the quantity can be fully specified by its magnitude alone, without any reference to a specific direction, then it is a scalar quantity.
