Front

What is speed?

Back

Speed is the distance traveled per unit of time, often measured in meters per second (m/s) or miles per hour (mph).

Front

What does it mean when an object is accelerating?

Back

Acceleration is the rate at which an object changes its speed or direction. It can be positive (speeding up) or negative (slowing down).

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

How can you determine if one object is moving faster than another?

Back

You can compare the distances traveled by each object in the same amount of time. The object that covers more distance is moving faster.

Front

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

Back

A flat line indicates that the object is not moving; it is stationary.

Front

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

Back

A steep slope indicates that the object is moving quickly; the steeper the slope, the faster the object is moving.

Front

What is the formula for calculating speed?

Back

Speed = Distance ÷ Time.

Front

What happens to travel time if speed decreases?

Back

If speed decreases, the travel time increases, assuming the distance remains the same.

Front

What is a distance-time graph?

Back

A distance-time graph is a visual representation that shows how distance changes over time for an object.

Front

What does it mean if a graph shows a downward slope?

Back

A downward slope on a distance-time graph indicates that the object is slowing down or coming to a stop.
