I want everyone to do well on the test tomorrow. That is why I gave you the practice word problems to do over the weekend. Unfortunately many of you didn’t do them, but you did have the opportunity to go over all of them in class today. In addition, we completed the Describing Motion worksheet, the one with the graph at the top.
Remember:
- Motion is a change in position relative to a reference point (are you on the bus or standing on the sidewalk?)
- Acceleration is a change in velocity (speed or direction) and can be positive or negative
- An object traveling in a circle at a constant speed is accelerating because it’s direction is always changing
- Displacement is a change in position (location)
- Speed is distance divided by time
- Velocity is speed and direction
- Acceleration is final velocity minus initial velocity, divided by time
Dear Mr. Grant,
I’m glad and both sad that I left your class. Glad because I wanted to have a chance to meet a new science teacher and learn his/hers lessons and different ways to learn things. I’m sad because I perfer to be in your class rather than where I am right now. I’m having trouble learnig the material so I decided to come and visit the site. It’s really helpful. I hope I pass the test.
Your Former Student,
Jennifer Polexi
