When you start learning about kinematics, there are some important equations that are really useful. Here are the key ones to remember:

1. First equation of motion:
   $v = u + at$
   This equation helps you find the final speed ($v$) if you know the starting speed ($u$), acceleration ($a$), and time ($t$).

2. Second equation:
   $s = ut + \frac{1}{2}at^2$
   This one calculates how far something moves ($s$) based on the starting speed, time, and acceleration.

3. Third equation:
   $v^2 = u^2 + 2as$
   This equation connects the speeds, acceleration, and distance moved without talking about time.

Knowing these equations will help you understand motion better. It also makes solving problems feel a lot easier!
