distance & speed
Some examples of scalars include temperature, speed, mass, and energy. Scalars are physical quantities that have a magnitude but no direction.
Physical quantities can be classified as scalars or vectors. Scalars have only magnitude, such as mass or temperature, while vectors have both magnitude and direction, like velocity or force. Scalars and vectors are further categorized into base quantities (e.g. length, time) and derived quantities (e.g. speed, acceleration).
Temperature Mass Time
Yes, scalars can be negative in mathematics. Scalars are quantities that have magnitude but no direction, so they can be positive or negative depending on the context in which they are used.
The two types of physical quantities are scalars and vectors. Scalars are quantities that only have magnitude, such as time, mass, and temperature. Vectors are quantities that have both magnitude and direction, such as velocity, force, and displacement.
