Speed & Motion Flashcard

Front

What is speed?

Back

Speed is the distance traveled per unit of time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What does a constant speed on a graph look like?

Back

A straight, diagonal line indicates constant speed.

Front

What is acceleration?

Back

Acceleration is the rate at which velocity changes over time.

Front

What does a decelerating object look like on a graph?

Back

A curve that slopes downwards indicates deceleration.

Front

What does a curved line on a distance-time graph indicate?

Back

It indicates that the object is accelerating.

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 is the unit of speed?

Back

The unit of speed is typically meters per second (m/s) or miles per hour (mph).

Front

What does it mean if an object is at rest?

Back

An object is at rest if it is not changing its position over time.

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed x Time
