Speed & Velocity Flashcard

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What additional information is needed to determine the velocity of an object?

Back

The direction in which the object is moving.

Front

What does a horizontal line on a distance-time graph represent?

Back

No motion; the object is stationary.

Front

What does a straight diagonal line on a distance-time graph indicate?

Back

Constant speed; the object is moving at a steady rate.

Front

What does a curve on a distance-time graph signify?

Back

Acceleration or deceleration; the object is changing its speed.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What does a negative acceleration indicate?

Back

The object is slowing down (decelerating).

Front

What is the formula for calculating average velocity?

Back

Average Velocity = Total Displacement / Total Time.

Front

What is displacement?

Back

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