Here’s a comparison of scalar and vector quantities, along with the classification for each of the measurements you listed:
| Measurement | Scalar/Vector | Definition |
|--------------------|----------------|--------------------------------------------------------------------------------------------|
| Mass | Scalar | A measure of the amount of matter in an object, independent of its location. |
| Speed | Scalar | The distance traveled per unit of time, without direction (e.g., 60 km/h). |
| Velocity | Vector | The rate of change of displacement with respect to time, including direction (e.g., 60 km/h north). |
| Displacement | Vector | The change in position of an object, represented by a straight line in a specific direction. |
| Force | Vector | A push or pull on an object that results from its interaction with another object, includes direction (e.g., 10 N upward). |
| Momentum | Vector | The product of an object's mass and its velocity, including direction (e.g., 50 kg·m/s west). |
| Work | Scalar | The transfer of energy when a force is applied over a distance, independent of direction (e.g., 100 J). |
| Kinetic Energy | Scalar | The energy possessed by an object due to its motion, defined as \( \frac{1}{2}mv^2 \), independent of direction. |
| Potential Energy | Scalar | The energy stored in an object due to its position in a force field (e.g., gravitational potential energy), independent of direction. |
In summary, scalar quantities are described only by their magnitude (size), while vector quantities are described by both magnitude and direction.
