Fast Facts Flashcard: Kinematics

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is the displacement of an object per unit of time, including direction, typically measured in meters per second (m/s).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, typically measured in meters per second squared (m/s²).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does the slope of a position-time graph represent?

Back

The slope of a position-time graph represents the velocity of the object.

Front

What does the area under a velocity-time graph represent?

Back

The area under a velocity-time graph represents the displacement of the object.

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken.

Front

What is instantaneous velocity?

Back

Instantaneous velocity is the velocity of an object at a specific moment in time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.
