- Elementary Definition of Standard Definite Integral
For constant C and n > −1, ∫[0→a] Cxⁿ dx = Caⁿ⁺¹/(n + 1), with a > 0. For n = −1 or n < −1, this improper integral diverges unless C = 0.

Acceleration
Acceleration is the vector rate of change of velocity with time. It can change an object’s speed, direction, or both, and it is measured in meters per second squared. For example, a satellite moving at constant speed in a circular orbit accelerates toward the center.

Velocity
Velocity describes how position changes with time and includes direction. Instantaneous velocity describes one moment, while average velocity is displacement divided by elapsed time. For example, a car turning a corner can change velocity while maintaining the same speed.
