- Okay!
- Gleiten: 2
- Hey Claire! Did you understand our lesson in physics earlier?
- Gleiten: 3
- So the velocity does not change?
- Gleiten: 4
- When that apple falls, it will undergo free-fall since gravity is pulling it toward the Earth.
- And all objects at free fall are exhibiting UAM, that's why I wanted to show it to you.
- Gleiten: 5
- Wow! That's amazing! I did not think it was just this easy to understand.
- Gleiten: 6
- Are you already going home, Claire?
- No problem.
- Gleiten: 0
- Mom! Claire and I are going to hang around here the garden!
- About the UAM?
- Yeah! You know, I did not clearly understand it
- Just trust me!
- Oh I see, come here an apple is about to fall from a tree.
- How is an apple going to help me understand it?
- In a Uniformly Accelerated Motion or UAM, the magnitude of the acceleration is constant.
- No Kate, it changes, just at a constant rate.
- Oh I get it, acceleration is the rate of how velocity changes over time. So in a UAM, the acceleration does not change or is constant since the velocity changes at a constant rate?
- You're right!
- What about this apple that is about to fall from the tree.
- Hmm??
- Why is it exhibiting UAM?
- It is because all free-falling objects, accelerate towards the Earth at a constant rate of 9.8 m/s^2 neglecting air resistance and regardless of its mass and weight.
- Is it true for all free-falling objects?
- Yes.
- Yeah it really is, sometimes, it's just around us like a ball rolling down a slope that also exhibits UAM.
- I understand now Claire, thanks for helping me. And I'm sorry for ruining our supposed to be relaxation afternoon.
- It's okay Kate, I'm happy to help you.
- Yes Mrs. Garcia, thank you for letting me come over.
- Mom. I'm just going to see Claire off.
