How does gravity affect the weight of an object on the moon compared to on Earth?

• The weight of an object on the moon is about 6 times its weight on Earth.

• The weight of an object on the moon is about 1/6th of its weight on Earth.

• The weight of an object on the moon is the same as its weight on Earth.

• The weight of an object on the moon is about 1/2 of its weight on Earth.

Explain how gravity affects the motion of a falling object.

• Gravity pushes the object upward, causing it to decelerate away from the Earth.

• Gravity causes the object to move sideways instead of downward.

• Gravity has no effect on the motion of a falling object.

• Gravity pulls the object downward, causing it to accelerate towards the Earth.

Explain the concept of free fall in relation to gravity.

• Free fall is the motion of an object where air resistance is the only force acting upon it

• Free fall is when an object is pushed upwards against gravity

• Free fall is the motion of an object where gravity is the only force acting upon it.

• Free fall is the motion of an object with no force acting upon it

• Apples falling from trees, a ball rolling down a hill, and a person jumping up and then coming back down

• A car driving on a flat road

• A bird flying in the sky

How does gravity impact the tides in the oceans?

• Tides are caused by the wind patterns in the atmosphere.

• Gravity from the earth creates tides in the oceans.

• Gravity from the moon and the sun creates tides in the oceans.

• Tides are caused by the rotation of the earth.

Discuss the role of gravity in keeping the atmosphere of Earth in place.

• The atmosphere of Earth is kept in place by the rotation of the planet

• Gravity plays a crucial role in keeping the atmosphere of Earth in place.

• Gravity has no effect on the atmosphere of Earth
