Gravity is a force between any two objects with mass. Why doesn't a person feel a gravitational force between him/herself and another person?
A person doesn't exert a gravitational force.
The two gravitational forces cancel each other out.
The gravitational forces of people is so small it is overshadowed by that of Earth.
There are so many people we are actually balanced by all the different gravitational forces.
The moon orbits our Earth. The opposite would never be true; the Earth would never orbit the moon. One reason is due to the force of gravity. The object ____________ has a greater gravitational force and that determines what satellites orbit around it
with the greater mass
containing mostly water
with a thicker atmosphere
with the greater diameter
Which two factors affect the strength of the gravitational pull between two objects?
Weight and Distance
Mass and Distance
Weight and Density
Mass and Density
Which best describes why gravity on Earth has a stronger attraction with you than the Sun has?
Earth has more mass than the Sun, allowing a stronger attraction to form.
The Sun has more mass than Earth.
Earth has a smaller mass than the Sun, but it is much closer to you than the Sun, allowing for a stronger attraction.
Earth has more magnetism than the Sun.
The greater an object’s mass, the greater its pull of ____________.
gravity
repulsion
The force of gravity _______________ objects and pulls them towards Earth.
attracts
repels
distances
does not change
An astronaut travels to the moon. What is true regarding her mass and weight?
Her mass and weight are greater on Earth.
Her mass and weight are the same on the moon as on Earth.
Her mass is the same on the moon and Earth, but her weight is greater on Earth.
Her weight is the same on the moon and Earth, but her mass is greater on Earth.
When will the forces of gravity between two objects be the GREATEST?
when the masses of both objects are small and the objects are far apart
when the masses of both objects are large and the objects are close together
when the masses of both objects are small and the objects are close together
when the masses of both objects are large and the objects are far apart
A compass behaves as it does because each needle acts as a(n) ___________.
Magnet
Guide
The area of magnetic force around a magnet is known as its _____________.
magnetic field
magnetic declination
magnetic fan lines
magnetic tan lines
How does Earth’s magnetic field compare with that of a bar magnet?
their magnetic fields increase with size
the attractive force of the magnetic fields is greatest at the poles
the attractive force of their magnetic fields is greatest at the center
electric current causes them to lose magnetism
Which of the following best describes a magnetic field?
a measure of the length of the magnet
an invisible region that surrounds the north pole of a magnet
an invisible region that surrounds the north pole of a magnet
a region around a magnet in which you can measure magnetic forces
Rubbing a balloon on your sweater can create static electricity.
true
false
After rubbing a balloon on your sweater, you are able to pick up small pieces of tissue paper. Why?
Rubbing the balloon created a gravitational field and the paper was attracted to it.
Rubbing the balloon created a magnetic field and the paper was attracted to the poles.
Rubbing the balloon created an electric field and the paper was attracted to it.
