What are scalar quantity and vector quantity with example?

Scalar quantity is a physical quantity that has only magnitude and no direction. Examples of scalar quantities include mass, temperature, speed, and energy.

Vector quantity is a physical quantity that has both magnitude and direction. Examples of vector quantities include displacement, velocity, acceleration, and force.

Scalar Quantity

- Definition: A scalar quantity is a quantity that has only magnitude and no direction.
- Examples:
- Mass (kg)
- Temperature (°C)
- Speed (km/h)
- Time (s)
- Energy (J)

Vector Quantity

- Definition: A vector quantity is a quantity that has both magnitude and direction.
- Examples:
- Velocity (m/s, km/h in given direction)
- Displacement (m, km in given direction)
- Acceleration (m/s², km/h² in given direction)
- Force (N, in given direction)
- Electric field (V/m, in given direction)
