Which of the following is a scalar quantity?
Speed
Distance
Both
Neither
Acceleration describes the time rate of change of:
Direction
Velocity
Inertia
Distance
Displacement
Which of the following explains why a positive acceleration does not always indicate an increase in the magnitude of velocity?
Acceleration is calculated from instantaneous velocity, and that value is typically positive.
Horizontal velocity is independent of gravity.
Positive acceleration always indicates an increase in the magnitude of velocity.
Gravity is usually negative.
Acceleration of a body can reflect a change in the velocity direction.
If an object’s initial coordinates are (3, 5, 0), and the final coordinates are (6, –2, –4), what is the object’s displacement?
3 units right, 3 units down, and 4 units forward
9 units right, 7 units down, and 4 units backward
3 units left, 7 units up, and 4 units forward
3 units right, 7 units down, and 4 units backward

In mechanics, acceleration may be used to describe:
A change in motion of a body at rest or in motion.
An increase in speed of a body at rest.
A change in direction of a moving body,
All of the above.
