Lesson Worksheet: Gravity Science
In this worksheet, we will practice describing the effects of gravity on objects that have mass, and how gravity allows planets to orbit stars.
Q1:
The picture shows two rocks in space. How close together must the rocks be for gravity to pull them toward each other?
- AThey must be touching.
- BThey have to be less than 1 meter apart.
- CThey have to be less than 10 kilometers apart.
- DThey have to be less than 10 meters apart.
- EThey can be at any distance from each other.
Q2:
The given picture shows three bags of sugar on a table. One bag of sugar has a mass of 500 g, another has a mass of 1 kg, and another has a mass of 2 kg. Which bag of sugar experiences the greatest force due to the gravitational pull of Earth?
- AThe 2 kg bag of sugar
- BThe 1 kg bag of sugar
- CThe 500 g bag of sugar
Q3:
Which of the following statements is true?
- AGravity is always a repulsive force.
- BGravity is always an attractive force.
- CGravity is sometimes an attractive force and sometimes a repulsive force.
Q4:
Which of the following statements is true?
- AGravity only acts on objects that are not moving.
- BGravity acts between all objects that have mass.
- CGravity only acts on objects that are in contact.
- DGravity only acts on objects that are moving.
Q5:
Complete the following sentence: The Moon is in the Earth’s gravitational .
- Aregion
- Bfield
- Cvolume
- Dzone
- Earea
Q6:
Complete the following sentence: An object is within the gravitational field of a planet .
- Aonly if it is in the atmosphere of the planet
- Bonly if it is on the surface of the planet
- Conly if it is orbiting the planet
- Dif it is experiencing the planet’s gravitational pull
Q7:
The picture on the left-hand side shows two rocks that are close to each other in space. The picture on the right-hand side shows the same two rocks closer together.
Which of the following statements is true?
- AThe gravitational force between the two rocks is greater when they are closer together.
- BThe gravitational force between the two rocks is greater when they are farther apart.
Q8:
A planet in a distant star system, called Ugantu, has two moons, called Velea and Kuthea. The two moons have the same mass, but Velea orbits the planet closer than Kuthea does. Which moon experiences a greater gravitational attraction due to the planet?
- AKuthea
- BVelea
Q9:
A planet in a distant star system, called Ulmara, has two moons, called Rovora and Maruta. The two moons orbit at the same distance away from the planet, but Rovora has a greater mass than Maruta. Which moon experiences a greater gravitational attraction due to the planet?
- AMaruta
- BRovora
Q10:
The given picture shows two apples hanging from the branch of a tree. One of the apples has a mass of 70 g. The other apple has a mass of 100 g. The centers of the apples are at the same height above the ground.
Which apple experiences a greater force due to the gravitational pull of Earth?
- AThe 100 g apple
- BThe 70 g apple
