Speed and Motion

Front

What does positive acceleration mean?

Back

Positive acceleration refers to an increase in speed over time, indicating that an object is speeding up.

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What does a graph with a straight line indicate about motion?

Back

A straight line on a graph indicates constant speed.

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 does it mean when an object is at rest?

Back

An object is at rest when it is not moving and its position does not change over time.

Front

What is acceleration?

Back

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

Front

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

Back

A downward slope indicates that the object is returning to its starting point.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

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

Back

A horizontal line indicates that the object is moving at a constant speed.

Front

What is the significance of the slope in a distance-time graph?

Back

The slope of a distance-time graph represents the speed of the object.
