What is required to know the velocity of an object? 😚
The time and the distance! 😉
A high intensity sound wave has a large _________
Amplitude! 😉
When the force of air resistance equals the force of gravity, a falling object reaches ________ velocity
Terminal! 👨🌾
If you walk around a square block going at the same pace, how many times does your velocity change and how many times does your speed change? ಥ_ಥ
Your velocity changes four times (because you are walking in a different direction on each side of the block). You are going at the same pace the entire time so your speed doesn't change! :)
🤔 Explain why motion is relative. Give an example.
Motion is relative because it is always described in relation to a reference point, we don't see the earth rotating because everything around us is moving with it (including us!) 🎩🙂🤗😏ಥ_ಥ(┬┬﹏┬┬)...
If a truck driver is driving at 30 kilometers per hour and she makes a U-turn, then starts driving at 30 kilometers per hour in the opposite direction, did the driver's speed or velocity change after changing direction? why? ¯\_(ツ)_/¯
The driver's velocity changed because the driver changed directions the driver's speed did not change. ☺️༼ つ ◕_◕ ༽つ
