Unit 2 - Lesson 4 - Gravity 2.0

Imagine Benjamin is conducting an experiment by placing an object exactly halfway between the Earth and Moon. What statement is most true for the object in this scenario?

• The object would be accelerating towards the moon

• The object would be accelerating towards the Earth.

• The object would be in a state of free fall

• The object would experience no gravitational force

During a beach outing, Maya noticed that the tides were higher when the moon was closer to the Earth. She wondered, why does the moon have a greater effect on the earth's tides than the sun?

• The moon is closer to the Earth and has a stronger gravitational pull

• The sun and moon have an equal effect on the tides

• The sun is actually closer to the Earth than the moon

• The sun's gravitational pull is stronger than the moon's

Imagine Jackson, Nora, and Michael each took a scale and weighed an apple on the Moon, Mars, and Earth respectively. What best explains why the apple would weigh different amounts on each celestial body?

• Surface temperature

• Atmospheric pressure

• Gravitational pull of each celestial body is different

• Distance from the Sun

Imagine Abigail drops a ball on Earth and it accelerates at 9.807 m/s². If she then drops the same ball on Jupiter, it accelerates at 24.79 m/s². What explains this difference in acceleration?

• The ball will accelerate at the same rate on Earth and Jupiter

• The ball will decelerate on Earth and accelerate on Jupiter

• The ball will not accelerate on either Earth or Jupiter

• The ball will accelerate faster on Jupiter because it has a stronger gravitational pull

If Zoe drops an apple from a height, what will happen to the apple under Earth's gravitational force?

• It will float away into space

• It will be pulled towards the center of the Earth

• It will be repelled by the Earth

• It will turn into a shooting star

Why do astronauts appear to be floating inside their space ship?

• It's an illusion

• They are moving at the same rate as the space ship

• Atmosphere inside the space ship

• Anti-gravity device that makes space travel possible

If you are sitting in a car that comes to a sudden stop, what best describes what you feel happening?

• You feel weightlessness

• You feel gravity pulling you back

• You feel friction pushing you sideways

• You feel your body continuing to move forward

What best describes gravity?

• A force that only affects objects in space

• A force that attracts objects with mass towards each other

• A force that has no effect on objects with mass

• A force that repels objects with mass away from each other

Liam's suitcase has a weight of 100 kg at sea level. What would be true if you weighed it at 30,000 feet?

• The suitcase would weigh more than 100 kg at 30,000 feet

• The suitcase would weigh the same at 30,000 feet as it does at sea level

• The suitcase would disappear at 30,000 feet

• The suitcase would weigh less than 100 kg at 30,000 feet
