Random 1
Earth rotates on its axis this many times every 24 hours.
once
This happens to the length of shadows in the afternoon compared to noon
shadows are longer in the afternoon
This ancient model tell us that the earth is the center of our solar system and everything orbits the sun.
Geocentric Model
This imaginary line runs through the Earth from the North Pole to the South Pole and is the axis around which the Earth rotates
axis
What are the gasses that surround Earth?
Atmosphere
What do you call the force going in the opposite direction of the object moving?
Resistance
Give an example of gravity
What cause earth to orbit around the sun?
What cause the moon to orbit around the Earth?
The sun's gravitational pull.
The Earth's gravitational pull.
Earth takes this long to complete one full orbit around the sun.
365.25 days
The apparent movement of the sun across the sky is actually caused by this
rotating on its axis
This model tells us that the sun is the center of our solar system and all the planets orbit the sun
heliocentric model
a group of stars that form a recognizable shape
constellation
What is the amount of matter in an object called?
mass
What do you call an increase in the rate of something?
acceleration
Give an example of Force
If two objects are closer together their gravitational force will be __________. Objects with less mass will have a ________ gravitational force.
stronger, weaker
As the Earth orbits around the sun, it also does this, causing the cycle of day and night.
rotating on its axis
What phenomenon causes us to see different constellations at different times of the year?
Earth's Orbit
What ancient Device was used to tell time of the day based on shadows
sundial
What do you call the measurement that depends on the pull of gravity on an object?
Weight
What do you call the force that accelerates (or pulls) an object toward the center of Earth?
Gravity
Give an example of Resistance.
If two objects with different masses are dropped from the same position, which object will reach the ground first? (pretend there is no air resistance) Why?
They will fall at the same time becuase gravitational acceleration is the same for all objects on the same on Earth.
A tool that provided evidence that earth is rotating.
Foucault pendulum
Why are scale models impractical to use when making models of space
because of size and distance
What do you call any interaction that can change the motion of an object.
Force
What was Isaac Newton known for?
He was known for his three laws of motion.
What is an example of an affect the moon's gravitational pull has on Earth.
High tides.
If I drop a feather and a a bowling ball how come the bowling ball falls first even though gravitational acceleration is the same for both objects on Earth?
Because of Air resistance.
Earth’s rotation causes these observable patterns, including day, night, and changes in the length of this throughout the day
Shadows
It takes only 87 days for this planet to complete one orbit around the sun
Mercury
This is used to make sure that everyone around the has noon when the sun is at it's highest point for them.
Time zones
It takes 12 years for this planet to complete one orbit around the sun
Jupiter
Who is the Italian Astronomer that dropped two objects with different massed from the Leaning Tower of Pisa? What did this prove?
Galileo
What did Newton's Law of Universal Gravitation say?
The more massive an object the stronger the gravitational force. And the further the objects are from each other the weaker the gravitational force.
Give two examples example on how weight can change? Why does it change?
If you stand on a tall mountain. If you go to another planet/ moon.
What is the difference between weight and mass?
Weight is the gravitational force on an object, while mass is the amount of atoms or matter in an object.
