Flashcards on Kinematics in One Dimension
Click on the flashcard to see the answer
What is kinematics in one dimension?
The study of motion in a straight line with no regards to its cause.
What is displacement?
The change in position of an object in a particular direction.
What is velocity?
The rate of change of displacement with respect to time.
What is speed?
The rate of change of distance with respect to time.
What is acceleration?
The rate of change of velocity with respect to time.
What is the equation for average velocity?
Average velocity = Change in displacement / Change in time
What is the equation for average speed?
Average speed = Total distance / Total time
What is the equation for acceleration?
Acceleration = Change in velocity / Change in time
Does a positive velocity imply motion in the positive direction?
Not necessarily, it depends on the chosen coordinate system.
What does a negative acceleration indicate?
A decrease in velocity or opposite direction of motion.
What is the equation to calculate final velocity?
Final velocity = Initial velocity + (Acceleration * Time)
What is the equation to calculate displacement using initial velocity, time, and acceleration?
Displacement = (Initial velocity * Time) + (0.5 * Acceleration * Time^2)
What is the equation to calculate final velocity squared using initial velocity, displacement, and acceleration?
Final velocity^2 = Initial velocity^2 + (2 * Acceleration * Displacement)
What is the equation to calculate acceleration using final velocity, initial velocity, and displacement?
Acceleration = (Final velocity^2 - Initial velocity^2) / (2 * Displacement)
What is the equation to calculate time using initial velocity, final velocity, and displacement?
Time = (Final velocity - Initial velocity) / Acceleration

Check Answers
Which equation can be used to calculate the final velocity?
Final velocity = (Initial velocity + Acceleration) * Time
Final velocity = Initial velocity * Time + Acceleration
Final velocity = Initial velocity + (Acceleration * Time)
Final velocity = Initial velocity - (Acceleration * Time)
Check Answers
What is the equation to calculate displacement using initial velocity, time, and acceleration?
Displacement = Initial velocity * Time + (0.5 * Acceleration * Time^2)
Displacement = Initial velocity + (0.5 * Acceleration * Time^2)
Displacement = (Initial velocity * Time) + (0.5 * Acceleration * Time^2)
Displacement = (Initial velocity + Acceleration) * Time^2
Check Answers
What is the equation to calculate final velocity squared using initial velocity, displacement, and acceleration?
Final velocity^2 = Initial velocity^2 + (2 * Acceleration * Displacement)
Final velocity^2 = Initial velocity^2 + (2 * Displacement / Acceleration)
Final velocity^2 = Initial velocity^2 + (2 * Acceleration * Displacement)
Final velocity^2 = Initial velocity^2 + (Displacement / Acceleration)
Check Answers
What is the equation to calculate acceleration using final velocity, initial velocity, and displacement?
Acceleration = (Final velocity - Initial velocity) / (Initial velocity * Displacement)
Acceleration = (Final velocity - Initial velocity) / (Final velocity^2 - Initial velocity^2)
Acceleration = (Final velocity^2 - Initial velocity^2) / (2 * Displacement)
Acceleration = (Final velocity^2 - Initial velocity^2) / (Displacement / 2)
Check Answers
What is the equation to calculate time using initial velocity, final velocity, and displacement?
Time = (Final velocity - Initial velocity) / (Displacement - Initial velocity)
Time = (Final velocity - Initial velocity) / (Acceleration * Displacement)
Time = (Final velocity - Initial velocity) / Acceleration
Time = (Final velocity - Initial velocity) / (2 * Acceleration)
Check Answers
Which of the following is true about velocity?
Always positive for motion in one dimension
Always negative for motion in one dimension
