Front

What does it mean when an object is accelerating?

Back

An object is accelerating when it is increasing its speed over time.

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time.

Front

If a toy car moves 1.2 km in 6 minutes, what is its speed?

Back

12 km/h.

Front

What is constant speed?

Back

Constant speed means the object covers the same distance each second without changing speed.

Front

What does it mean when an object is decelerating?

Back

An object is decelerating when it is decreasing its speed over time.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

In which segment is the speed greatest if the segments are A-B, B-C, C-D, and D-E?

Back

C-D.

Front

What happens to an object's speed if it is moving at a constant speed?

Back

The object's speed remains the same over time.

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).
