Contact Force
Non-Contact Force
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
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
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
More mass = More inertia
True
False
According to Newton's second Law, which would take more force to slow down?
The silver car
The green car
They would both take the same force
If the amount of force doubled, what would happen to the acceleration of the object?
The acceleration would decrease
The acceleration would increase
Nothing would happen to the acceleration
