PHYSICS 201 MODULE 05.1D KINEMATICS EXPECTED
QUESTIONS WITH VERIFIED ANSWERS
Question 1.
If an object's acceleration vector points in the same direction as its instantaneous velocity vector
then you can conclude __________.
ANSWER
the object is speed up
Question 2.
This position versus time graph represents the motion of an object moving in a straight line. What is
true about the object's motion?
ANSWER
The object is at rest.
Question 3.
A ball is dropped off of a tall building and falls for 2 seconds before landing on a balcony. A rock is
then dropped from the top of the building and falls for 4 seconds before landing on the ground.
How does the final speed (meaning the speed it had just before landing) of the rock compare to the
final speed of the ball?
ANSWER
The rock's final speed is twice as much as the ball's final speed
Question 4.
If an object's acceleration vectors points in the opposite direction of the instantaneous velocity
vector, then you can conclude
ANSWER
the object is slowing down
Question 5.
This velocity versus time graph exhibits what kind of motion?
1/5
, ANSWER
An object moving at a constant speed
Question 6.
This position versus time graph exhibits what kind of motion between points Q and R?
ANSWER
A moving object that is speeding up
Question 7.
Which of these equations is the correct mathematical representation of this position versus time
graph?
ANSWER
x=xi+vt
Question 8.
The motion of two cars, A and B, is described with these position versus time graphs. From these
graphs, what can you conclude about the motion of the cars?
ANSWER
Car A is driving at a faster constant speed than car B.
Question 9.
Which of these equations is the correct mathematical representation of this velocity versus time
graph?
ANSWER
v=vi_at
