Inertia is a force
True
False
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
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
While you’re ice-skating with your friends, you push off from one end of the rink and slide forward. Based on Newton’s first law of motion, what is true?
You will lose your balance and fall over before you reach the middle of the ice rink.
You will continue to slide across the ice until a force makes you stop or change direction.
The force of gravity will make you keep your velocity until your friend makes you stop.
The size of your ice skates will determine how quickly or slowly you travel across the ice.

The tablecloth is an ilusion.
The dishes have inertia, and therefore stay on the table.
magic
