1. What do you think the difference between weight and mass is?

2. When you're in a car that is making a sharp turn, why does your body feel pulled in the opposite direction of the turn?

3. What shape is the Earth's orbit around the Sun?

Brain Teaser:

Paul the butcher is 5 feet tall

Has 4 shoes, they're size 5 all

His 2 eyes grey, his hair is blue

And so I have a quiz for you.

We know all of Paul that's on display,

except.. what has Paul weighed all day?

1 "lap" = 1 orbital PERIOD

1 period = 1 year

Smaller orbit = shorter year

Visual Aid (page 8)

Purpose:

Model the forces of motion.

LEQs:

What are the “rules” that moving objects, like planets, follow?

(page 8)

Law of Equal Areas

Focus

Both areas are equal.
