The correct answer is: C. Meter per second square.
Jerk is the rate of change of acceleration. It is a vector quantity, meaning it has both magnitude and direction. The SI unit of jerk is meter per second squared (m/s^2).
Option A, meter second, is not a unit of jerk.
Option B, meter per second cube, is the unit of acceleration.
Option D, meter per second, is the unit of velocity.
Jerk is important in physics because it is a measure of how quickly an object’s acceleration is changing. This can be important in many applications, such as when designing vehicles or when studying the motion of objects in space.
