Inertia is a force
True
False
Suppose that an astronaut throws a baseball in outer space at a location far from significant influences of gravity and air resistance. One would expect that the baseball would ____.
eventually stop since all objects ultimately "lose their steam"
eventually stop as its inertia slowly becomes used up
continue in motion with the same speed and direction
either a, b, or c -- depending on whether the astronaut continues to push it
Inertia is a force that keeps stationary objects at rest and moving objects in motion at a constant velocity.
True
False
When all individual forces acting on an object are balanced, it is the natural tendency of an object to _____. List all that apply in alphabetical order with no spaces between letters.
maintain its state of motion
eventually stop
accelerate
either speed up, slow down or keep the same speed
keep its velocity constant (either at a zero or non-zero value)
The law of inertia (Newton's first law) applies _____.
to moving objects only
only to objects that are not moving
to both moving and nonmoving objects
Inertia refers to _____
the tendency of moving objects to remain in motion
the force which keeps moving objects in motion with a constant velocity
the force that keeps stationary objects at rest
the tendency of stationary objects to remain at rest
A skateboard rolls down a hill, reaches the level surface and eventually comes to a stop. The fact that the skateboard ultimately stops is best explained by ____.
an unbalanced force would be required to keep the sled moving forward at constant speed
the presence of an unbalanced force (e.g., friction) can cause a moving object to stop
the presence of inertia causes it to stop
the natural tendency of any object is to ultimately stop
Inertia depends on ______
Velocity
Speed
Distance
Mass
All objects have inertia
True
False
List the objects in order from least to greatest inertia.
CDBA
ABCD
BCDA

Mr. S guides a golf ball around the outside rim of the green at the Hole-In-One Putt-Putt Golf Course. When the ball leaves the rim, which path (J, K, or I) will the golf ball follow?
J
K
I
Mac and Tosh are arguing in the cafeteria. Mac says that if he flings the jello with a greater speed it will have a greater inertia. Tosh argues that inertia does NOT depend upon speed, but rather upon mass. Who is correct?
Mac
Tosh
Neither
Both
An astronaut kicks a soccer ball in outer space at a location far from significant influences of gravity and air resistance. The soccer ball will _________.
continue in motion with the same speed and direction
eventually stop as its inertia slowly becomes used up
eventually stop since all objects ultimately "lose their steam"
either a, b, or c -- depending on whether the astronaut continues to kick it
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a(n) ____________________.
unbalanced force
inertia
mass
balanced force
A rightward-moving object would naturally and ultimately come to rest in the absence of forces. A rightward force is required to keep such an object moving rightward. Inertia is the general name given to that force.
True
False
More mass = More inertia
True
False
Rank these objects in order of their inertia, from greatest to least.
ABCD
DABC
DCBA
CBAD
