This quiz contains 13 questions from a mix of 1 subtopics.
How do gravitational fields exert forces on objects?
through repulsive forces
gravitational fields do not exert forces on objects
through physical contact
through attractive forces without physical contact
|
Which of the following typically produces noticeable gravitational fields?
small objects like a tennis ball
neither small objects nor large masses
large masses like planets
both small objects and large masses
|
What do gravitational field lines represent?
both the direction and strength of the gravitational field
the direction of the gravitational field
the path a small object would follow under gravity's influence
the strength of the gravitational field
|
In which direction do gravitational field lines point?
perpendicular to the mass creating the field
towards the centre of the mass creating the field
in a random direction
away from the centre of the mass creating the field
|
What does it indicate when gravitational field lines are close together?
the direction of the gravitational field
a strong gravitational field
a weak gravitational field
the absence of a gravitational field
|
What does it signify when gravitational field lines are spaced further apart?
a strong gravitational field
the direction of the gravitational field
a weak gravitational field
the absence of a gravitational field
|
What happens to the gravitational force as an object moves further from Earth?
the force increases
the force decreases
the force remains constant
the force fluctuates randomly
|
How does the strength of the gravitational field of small masses compare to that of large bodies like Earth?
the strength of the gravitational field is not related to the mass of the object
small masses have stronger gravitational fields
small masses have weaker gravitational fields
small masses and large bodies have equally strong gravitational fields
|
What does the parallel alignment of gravitational field lines close to a large mass like Earth indicate?
a non-uniform gravitational field
the absence of a gravitational field
a uniform gravitational field
the direction of the gravitational field
|
Assuming a uniform gravitational field is a useful simplification in which of the following situations?
when dealing with objects near the Earth's surface
when dealing with objects far from the Earth's surface
when dealing with objects in space
when dealing with objects on other planets
|
Which of the following is an example of the effect of gravitational fields on Earth?
ocean tides
the Earth's rotation
the Earth's magnetic field
the change of seasons
|
Explain how the spacing of gravitational field lines relates to the strength of the gravitational field.
|
Explain how gravitational fields exert forces on objects and provide an example of this effect on Earth.
