Given a formula v squared=u squared±2as and 1/2at squared
To understand the given formula, let's break it down:
1. Formula: v^2 = u^2 ± 2as
- This formula calculates the final velocity (v) of an object in motion when you know the initial velocity (u), acceleration (a), and displacement (s).
- The ± sign indicates that there are two possibilities for the formula depending on the situation:
- If the object is decelerating (slowing down), you use the negative sign: v^2 = u^2 - 2as.
- If the object is accelerating (speeding up), you use the positive sign: v^2 = u^2 + 2as.
2. Formula: (1/2)at^2
- This formula calculates the displacement (s) of an object in motion when you know the initial velocity (u), time (t), and acceleration (a).
- Here it is multiplied by a factor of (1/2) to calculate the displacement due to constant acceleration over time.
