Speed, Velocity, and Acceleration

Front

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

Back

The object is not moving.

Front

What is speed in a given direction called?

Back

Velocity.

Front

In a distance vs. time graph, what type of motion does an upward sloping line represent?

Back

Acceleration.

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time.

Front

What is acceleration?

Back

The rate of change of velocity per unit time.

Front

What does a steep slope on a distance-time graph indicate?

Back

Higher speed.

Front

What is the difference between speed and velocity?

Back

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

Front

What does a negative acceleration indicate?

Back

The object is slowing down.

Front

What is the unit of acceleration in the SI system?

Back

Meters per second squared (m/s²).

Front

How can you calculate average speed?

Back

Average Speed = Total Distance / Total Time.
