between the displacement and the distance traveled - -The displacement is either less
than or equal to the distance travel
-When an object is released from rest and falls in the absence of friction, which of the
following is true concerning its motion? - -Its acceleration is constant

-A component of a vector can be greater than the vector's magnitude. - -False
-If A+B = C (all vectors) and A^2 + B^2 = C^2, then the vectors A and B are oriented
perpendicular relative to one another. - -True
, -The magnitude of a unit vector is one. - -True
-The horizontal component of the velocity of a projectile remains constant during the
entire trajectory of the projectile. - -True

- -is constant
-A force is required for an object to accelerate. - -True
-The acceleration of an object does not have to be in the same direction as the net force
applied to it. - -False
-A force is required to keep an object moving along a horizontal line. - -False
-The mass of an object is fixed, but its weight varies from location to location. - -True
-Your mass on the moon will be about one-sixth of your mass on Earth. - -False
-In the absence of an external force, a moving object will - -move with constant velocity
in a straight
-7) An object is moving with constant velocity in a straight line. Which of the following
statements is true? - -The net force on the object is zero.
-8) If you push a 4-kg mass with the same force that you push a 10-kg mass from rest,
then - -the 4-kg mass accelerates 2.5 times faster than the 10-kg mass.
-lf you exert a force F on an object, the force which the object exerts on you will - -
always be -F

makes an angle of 30 with the horizontal. Which statement best describes their
acceleration after being released? - -Both cars accelerate at a rate of g sin(30).
