## Projectile Motion Formula with Solved Examples

In this article, we have attempted to teach you the formulas for projectile motion by presenting some solved examples. Through this method, you will gain a better understanding of the equations for projectiles. Definition of projectile motion: Projectile motion refers to the motion of any object that is thrown into the air at an angle $\theta$. It is characterized by motion in two dimensions and is solely influenced by gravitational force.  Projectile Motion Formulas: The following equations represent projectile motion in the vertical and horizontal directions. In the horizontal direction: \begin{align*} \text{Displacement}&:\,\Delta x=\underbrace{\left(v_0 \c

## Acceleration on Position-Time Graph

How to find acceleration from a position vs. time graph?  Answer: in one word, the shape of the graph shows the acceleration. A straight line means zero acceleration. A curved line means non-zero acceleration. The steeper the curve, the bigger the acceleration. A bowl shape means positive acceleration (speeding up). An upside-down bowl means negative acceleration (slowing down).  In this article, you will learn how to find the acceleration from the position-time graph, both graphically and numerically, with some solved problems for grade 12 or college level.  You can skip this introduction and refer to the worked examples.    Types of Motion: An o
