- Okay Mom, I'll be right back.
- One summer, Alexa who is a Grade 9 student was tasked by her mother to run some errands for her.
- Fortunately, there was a nearby store in their town. So it won't be a hassle for Alexa anymore.
- As she was walking, Alexa passed passed by at their town's playground.
- Then, she observed a ball rolling on the slide.
- As Alexa was waiting for her order, her mind wandered back to the car she observed. Because of that, she was not able to recognize her Physics teacher, Mrs. Davis, in front of her.
- Earlier, the ball was rolling down constantly. Hmm, why is that?
- Hello, Ms. Alexa.
- Orders are now served!
- Mrs. Davis! I never thought I'll be meeting you in a place like this.
- Since you're here Ms. Davis, I will tell you about what I have observed earlier.
- Alexa explained her observation earlier to Mrs. Davis, her Physics teacher. After that, their orders were served at the same time.
- You seem to be in deep thoughts, Ms. Alexa. I can listen to your concerns .
- In definition, it is a condition where a body or a system of bodies moves at constant or uniform acceleration. This means that the velocity of the body changes at a constant rate.
- For example, what you saw is an example of UAM. A ball rolling on an inclined plane as well as objects at free-fall. They also exhibit UAM.
- Ms. Alexa, what you have observed a while ago is an example of Uniformly Accelerated Motion or UAM.
- The velocity of the object changes, but at a constant rate. 
- So do you understand now what is Uniformly Accelerated Motion, Ms. Alexa?
- A ball rolling on an inclined plane exhibits has a constant acceleration. It does not change.
