Please read chapter 6 - Skim 6.1-6.2 (ie, you do not need to take notes on vocab from these sections), focus more intently on 6.3-6.6, especially 6.6. What questions do you have?

Match the term: rotatation of an object with its orbit.

Stavka koja se može prevući		Odgovarajuća stavka
Synchronous rotation		Deformation caused by gravitational forces between celestial bodies
Tidal braking		Temporary dimming of one celestial body by another
Tidal bulge		Gradual slowing down of rotation due to tidal forces
Eclipse		Rotates at the same rate as orbit

How do astronomers believe the moon was formed?

Small planet orbiting the sun captured by the gravity of the Earth

The earth and moon formed side by side at the same time

The earth was spinning so fast a bulge came out and broke off from the earth

Something big crashed into earth, formed a cloud of stuff made from the earth and whatever hit it and that formed into the moon

1

The effect of tidal braking of the earth caused by the moon would eventually lead to

only one side of the earth facing the sun at all times

only one side of the earth would face the moon at all times

the moon rotating faster would mean the earth being able to see the dark side of the moon

the moon moving farther away from the earth

1

why will an astronauts' footprint last so long on the surface of the moon?

1

synchronous orbit is the reason that

the moon enters different phases through the month

we always see the same side of the moon

lunar eclipses don't happen every month

the moon doesn't have an atmosphere.

1

The sun produces a smaller tide than the moon, even though it is significantly larger than the moon. Why?

1

Which is the most accurate way to measure the distance to the moon?

Parallax

bouncing light off the moon

travelling to the moon

string

1

Notice that up until the point where man landed on the moon the only information we had about the moon came from light. We had several theories about the origin of the moon, but no way to prove anything. How did the moon landing change the scientific world from many theories to one accepted theory?

The explanation of tides in your book is fine. HOwever, everything is a little more complicated that that. What physics teachers get wrong about tides
Do you have any questions

The video says that if the center of the earth is the inertial frame of reference, the water at the far side from the moon moves further away from the center. If the inertial frame is the moon, however

The water on the far side isn't moving at all, just the center moves

water doesn't move on either side of the earth, if it did, rocks would levitate

the water on the far side moves towards the moon, just not as fast as the center of the earth moves towards the moon.

The moon is moving towards the earth

The tidal force video described tides as more a squeezing caused by pressure at the sides of the planet than stretching along the line from the planet to the moon. Can you define pressure?

1

how the moon was formed
why we never see the dark side of the moon
how bouncing light can measure the distance to the moon
what synchronous rotation means
how tidal braking works
the difference between a solar eclipse and a lunar eclipse
what causes the tides
Why the tidal force from the sun is less than the moon

ive got this
im fuzzy
so confused

Honors: If you want to decompose a vector into two perpendicular components using what you remember from basic trig back in geometry class, you would use the equations

Ax = A sin θ, Ay = Asin θ

A = Axsinθ, A = Aycosθ

Ax = A cos θ, Ay = A sin θ

θ = A sin Ax, θ = A cos Ay

You are in a car with your brother, who is tossing a ball up in the air. You pass your friend on the road. If you choose yourself as the inertial frame of reference do you feel like

you passed your friend, and your brother is moving down the road?

You and your brother are stationary and your friend and the street are moving backwards

the ball is moving in a parabolic path

you are not moving along the road, but your brother is

In order to watch the astronomy video I want you to see, you are going to need some basic physics. First - the idea of frames of reference.
Do you have any questions?

Spend a little time playing with this phet simulation (you may also want to work on it outside this formative so you can go full screen. here https://phet.colorado.edu/en/simulations/vector-addition/teaching-resources
try to add and subtract vectors in 1 d, add and subtract vectors in 2d.

A laser pulse takes 2.56 seconds to travel from earth to the moon and return. Given that the speed of light is 300,000 km per second, how far away is the moon?
Honors: you should be able to do this without the hint.
