What is a scaler quantity?
A scalar quantity is a physical quantity that has only magnitude and no direction. Examples include time, temperature, mass, and speed. Scalars are represented by a single numerical value.
Is work vector or scaler quantity?
Work is a scalar quantity, as it is described by a single value (the amount of energy transferred) and does not have a direction associated with it.
What is The rate of a changing quantity is the amount it changes per single increment of time?
The rate of a changing quantity is the derivative of that quantity with respect to time. It represents how fast the quantity is changing at a specific point in time. This rate can be constant or variable depending on the nature of the change.
