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
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
More mass = More inertia
True
False

increased
unbalanced
balanced
decreased
If a cannonball were launched into deep space (no friction or gravitational effects), how much force would be needed to keep the ball moving with a constant velocity?
A force equal to its weight.
No force would be needed.
A force large enough to balance friction.
150-N
What is the name of the missing force?
applied force
gravity
