📚 Quick Study Guide

📏
• Definition: Acceleration is the rate of change of velocity with respect to time.
⏱️
• Formula: Average acceleration is given by $a_{avg} = \frac{\Delta v}{\Delta t}$, where $\Delta v$ is the change in velocity and $\Delta t$ is the change in time.
➡️
• Direction: Acceleration is a vector quantity, meaning it has both magnitude and direction. The direction of the acceleration is the same as the direction of the change in velocity.
➕
• Constant Acceleration: For constant acceleration, we can use the kinematic equations:
• $v = v_0 + at$
• $\Delta x = v_0t + \frac{1}{2}at^2$
• $v^2 = v_0^2 + 2a\Delta x$
📉
• Deceleration: Deceleration is acceleration in the opposite direction of motion, causing the object to slow down.
