Final answer:
The unit of speed listed in the options is C) Meter per second (m/s), which indicates the distance an object travels in one second. The other units mentioned are for force, pressure, and energy.
Step-by-step explanation:
The unit of speed among the options provided is C) Meter per second (m/s). This unit represents how far an object travels in one second and is a compound unit derived by dividing a distance by time.
Unlike speed, the Newton (A) is the SI unit of force, the Pascal (B) is a unit of pressure, and the Joule (D) is a unit of energy. Speed is a scalar quantity indicating how fast an object is moving, whereas velocity is a vector quantity that describes both speed and direction of an object's motion.
SI units for velocity are also measured in meters per second (m/s), but velocity additionally requires a direction due to its vector nature.
Velocity, like speed, has SI units of meters per second (m/s), but because it is a vector, you must also include a direction. Other units for velocity include kilometers per hour (km/h) or even micrometers per nanosecond (μm/ns).
