Exam Questions With Correct Answers.
What is a vector? - answer✔✔A quantity that has magnitude and direction
For one-dimensional motion, by examining the slope of an object's position vs. time plot we can
find? - answer✔✔The object's velocity
What quantity is not a vector? - answer✔✔Speed
For one-dimensional motion, by examining the slope of an object's velocity vs. time plot we can
find? - answer✔✔The object's acceleration
An object is moving with a certain velocity. In order for the object to KEEP moving with the
same velocity there must be - answer✔✔No net force acting on the object, and NO push is
needed to keep the object going
The net force on an object points - answer✔✔In the same direction as the acceleration of the
object
In the same direction as the object's change in velocity
An action/reaction pair of forces - answer✔✔Point in the opposite direction
Act on two different objects
How do you find average velocity - answer✔✔Change in position/change in time
How do you find average speed - answer✔✔Total distance/total time
How do you find average acceleration - answer✔✔Change in velocity/change in time
A race car is traveling around a circular track in a clockwise direction with a constant speed of
200 km/hr. What is the instantaneous velocity of the car when it is at the westernmost point on
the track? - answer✔✔North?
If the acceleration is zero, the speed - answer✔✔Must be constant
If an object has a constant velocity, the net force acting on it - answer✔✔Must be zero
