8.6 B Physics STAAR Review (S,V,A, Motion Graphs)

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 speed of an object in a specific direction, combining both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time, indicating how quickly an object is speeding up or slowing down.

Front

What does a flat line on a motion graph represent?

Back

A flat line indicates that the object is at rest, meaning it is not moving.

Front

What does a steep line on a motion graph indicate?

Back

A steep line indicates that the object is moving at a high speed.

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 it mean if an object has a constant speed?

Back

It means the object is moving the same distance in equal intervals of time.

Front

What is a motion graph?

Back

A motion graph visually represents an object's position, speed, or acceleration over time.

Front

What does a downward slope on a motion graph indicate?

Back

A downward slope indicates that the object is moving backward or slowing down.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.
