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
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)
All objects have inertia
True
False
Inertia depends on ______
Velocity
Speed
Distance
Mass
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
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
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
More mass = More inertia
True
False

39 seconds
12 seconds
15 seconds
33 seconds
What is Newton's Third Law of Motion?
an object at rest stays at rest, and an object in motion will stay in motion until an outside force acts upon it
the acceleration of an object will be equal to the net force of an object divided by its mass
for every action, there will be an equal and opposite reaction
an object that is not moving will stay not moving moving until an unbalanced force acts on it
If a bird hit your windshield on your car, the force of the car on the bird equals
the force of the bird on your car.
the force of the car on the brid
an elastic collision on the windshield
a noncontact force acting on the windshield
If you throw a ball into the air, Earth exerts a force on the ball. The ball in the air exerts no force on Earth.
True; all forces act alone
False; there will always be a force pair
