0 of 2 Steps Completed- Instantaneous velocity and acceleration require calculus (derivatives) if the acceleration is not constant.
- In Projectile Motion, treat the horizontal and vertical motions as entirely independent problems linked only by time ().
- Relative velocity requires defining a reference frame and using vector addition/subtraction.
