- we began class with two short warmup questions related to gravity
- one question asked ... What do you think would happen if you rang out a soaked towel while on a spaceship?
- the other question asked ... Do you think it is possible to grow a plant on a spaceship?
Gravity Warmup
- I then showed the class the answer to both of their questions
What Happens When You Wring a Washcloth In Orbit
Plants Grow Fine Without Gravity
- before getting into notes I showed the students a MinutePhysics clip
- we then began to take our first set of notes for the unit Forces in Motion
Forces in Motion Notes
- gravity as a force of attraction was explained to the students
- it is not just the Earth pulling you towards the center of the Earth, you also pull the center of the Earth towards you!
- as mass increases gravity increases
- think of a weightlifter
- the more plates that are added, the more pull downwards from gravity
- as distance increases gravity decreases
- think of a long distance relationship
- the more distance the less attraction (for the most part :) )
- we also talked about the difference between mass and weight
- with the last few minutes of class the students were handed a reading and a half sheet of questions to complete for homework
