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