Yeah I got you.
Motion 1. Student will demonstrate an understanding of Newton’s Laws to one of three real-life situations.
In car driving forward book falls out of seat
Catching a basket ball
Bowlinig ball+pins
Motion 2. Student will demonstrate an understanding of motion, forces, and energy by using lab data to differentiate among the various forms of energy, describing the relationship between work and power, and by constructing a machine that identifies types of energy used and how energy is transformed from one form to another.

Explain in terms of frame of reference if you’re inside a moving train everything on the outside can seem to be moving.
frame of reference is a place or object that you assume is fixed.
Inside the train, train is reference point and eveything outside is looks in motion
What are Newton’s three laws of motion?
Inertia
f=ma
Every action has an opposite and eqal reaction
If you’re in a car moving at a high speed, and you stop abruptly, how would what happens be different with wearing a seatbelt as opposed to not wearing a seat belt? Which of Newton’s 3 laws would apply?
1st law inertia because when you stop apprulty your body wants to move forward but the seat belt stops you from doing so, without it you would fly forward and get hurt
What’s force? What’s the strongest of the four basic forces? What’s the weakest?
gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity
Use the example of a tug of war to explain the difference between balanced and unbalanced forces.
Balanded both are pulling eqaul forced and rope isnt moving
Unbalnced is one side is larger and rope is pulling
Using the Rube Goldberg device from the lesson or the one you designed, discuss the Law of Conservation of energy and give an example of energy transfer.
books faling into boucket
all of the energy available at the start of a conversion or transfer still exists in some form of energy after the change is complete.

Using the equation for work, if you push on a wall as hard as you can, have you done any work?
No, the wall is not moving
Use the relationship between work and power to discuss the amount of work done when a weight lifter lifts 25 lbs 1 m in 1 s and another lifts the same weight 1m in 2 seconds.
