Define Gravity
The force that pulls objects down towards the center
100
In what direction is gravity going to pull an apple that falls from the apple tree?
Downwards
100
What direction will something go in if no force acts upon it?
A straight line
100
Would I weight more or less on Jupiter? Why?
More, because of more gravity
100
What is the mechanism that allows us to see light from the moon?
Reflected Light
200
Define Mass
The amount of stuff/atoms in an object
200
What direction will gravity pull the buildings in this image?
Towards the center of Earth
200
What will happen to an object at rest if no force ever acts upon it
It will stay at rest
200
Would I weight more or less on the moon? Why?
Less, because of less gravity
200
The Earth's position in its orbit, coupled with the tilt in it's axis causes a strange natural phenomena called what to take place?
Seasons
300
Define Inertia
Objects at motion will stay in that motion in a straight line until an outside force acts against it.
Objects at rest will stay at rest until an outside force acts against it.
300
In what direction is gravity going to pull the planets?
Towards the Sun
300
What would happen to Earth while orbiting the Sun if there was suddenly no gravity?
It would fly out into space in a straight line
300
If my mass on Earth doubled, what would happen to my weight?
It would also double
300
Which side of Earth would the moon need to be for us to see a Full Moon?
The right side
400
Define Weight
The amount of gravitational force exerted on an object
400
What are the two largest factors that affect gravity?
Distance from Sun and planet mass.
400
If I am riding a bike and it suddenly stops, what will my body do and why?
It will keep going forward in a straight line because of inertia.
400
Why does Saturn have slightly less gravity than Earth despite having a higher mass?
Saturn is very far away from the Sun so it affects it's numbers
400
What type of eclipse is being shown here?
Solar Eclipse
500
What is the difference between weight and mass?
Mass is the amount of stuff matter is, while weight is the amount of gravitational force on an object. Mass never changes while weight changes with gravity.
500
The International Space Station is 254 miles away from the Earth. If you were on the International Space Station, what would happen to the gravitational pull from Earth as you travel further way from Earth?
It would decrease
500
If inertia is keeping the moon orbiting the sun, why isn't it flying away in a straight line?
Gravity
500
Are measurements for the further planets 100% accurate?
No. There is much we still don't know, which is why some scientists slightly disagree with some data.
500
Would this be summer in the northern or southern hemisphere? How do you know?
Northern.
Due to the tilt, it is receiving more direct sunlight per day.
