In "an object in motion tends to stay in motion", the word "motion" means
mass
force
acceleration
velocity
T or F? When an object accelerates, it must be changing speed.
true
false
T or F? When an object changes speed, it must be accelerating.
true
false
The force that maintains motion is
applied force
gravitational
inertia
Nonsense! No force is required to maintain motion.
Inertia means
no mass
no motion
no acceleration
no clue
These forces cause acceleration.
net
external
inertial
nonconservative
T or F? An object moving in a circle at a constant speed is accelerating.
true
false
T or F? An object moving in a straight line at a constant speed is accelerating.
true
false
Normal means
support
net
average
perpendicular
The weight of an object is
the same as the mass
the force exerted by gravity
inertia
independent of location
Newton's Second Law says
mg - T = ma
F = ma
Fnet = ma
W = mg
Friction opposes
motion
natural motion
circular motion
accelerated motion
A more massive object _______ has more inertia than a less massive object.
always
sometimes
never
T or F? Inertia is the tendency of all objects to resist motion and eventually come to a stop.
true
false
T or F? It would take a force to keep an object in motion at a constant velocity
true
false
T or F? Forces always cause objects to move.
true
false
T or F? A force is a vector quantity; there is always a direction associated with it.
true
false
T or F? An object that is moving rightward must have a rightward force acting on it.
true
false
T or F? If an object is moving right and slowing down, then the net force is directed left.
true
false
