To help you review kinematics for Grade 10 Physics, let's break down some important ideas:

1. Basic Definitions:

   • It’s important to know what velocity, speed, and acceleration mean.
   • Average speed tells us how fast something is going overall and is calculated with this formula:
     $v_{avg} = \frac{d}{t}$
     (where 'd' is distance and 't' is time).
   • Acceleration measures how quickly something speeds up or slows down, and it’s calculated like this:
     $a = \frac{Δv}{t}$
     (where 'Δv' is the change in velocity).

2. Equations of Motion:

   • Get to know these four important kinematic equations:
   • ( v = u + at ) (this shows how velocity changes over time)
   • ( s = ut + \frac{1}{2}at^2 ) (this helps calculate distance)
   • ( v^2 = u^2 + 2as ) (this relates velocity and distance)
   • ( s = \frac{(u + v)}{2} t ) (this finds average distance).

3. Graph Interpretation:

   • Learn how to read graphs that show displacement (how far something moves), velocity (how fast it moves), and acceleration (how quickly it speeds up).

4. Problem-Solving:

   • Try solving at least 20 practice problems. This will help you really understand the content.
   • Focus on situations like free fall (when something drops), projectile motion (when something is thrown), and different kinds of motion (moving straight up and down or side-to-side).

By learning these concepts, you’ll be better prepared for your physics tests!
