PHYSICS CHAPTER 1 EXAM REVIEW
QUESTIONS AND ANSWERS

order of magnitude estimate - Answer-a rough calculation that is off by a factor of two,
ten, or more, but may still be useful.

velocity - Answer-the speed and direction of a moving object

force - Answer-A push or pull exerted on an object

scalar quantity - Answer-A quantity in physics, such as mass, volume, and time, that
can be completely specified by its magnitude, and has no direction.

vector quantity - Answer-A physical measurement that has both a direction and
magnitude.

magnitude - Answer-measurement of size, length, temperature, etc. The "how big" or
"how much". Scalar quantity, always positive.

discplacement - Answer-change in a position of an object. Includes how far the object
moves and the direction. e.g. walking 3 km north.

Is NOT directly related to total distance traveled. e.g. a ball that is thrown has a curved
path and has a larger total distance than the total displacement or an object that returns
to its original position will have a displacement of zero even though it has traveled some
distance.

parallel vectors - Answer-two vectors that have the same direction. (regardless of
magnitude)

negative of a vector - Answer-a vector that has the same magnitude as another vector
but is pointing in the opposite direction

antiparallel vector - Answer-two vectors that have opposite directions (regardless of
magnitude)

vector addition - Answer-the combining of vector magnitudes and directions. Can be
calculated graphically using tip to tail method or parallelogram method. Can be
calculated algebraically by adding each vectors x,y,z components.

resultant vector - Answer-the vector sum of two or more vectors.
