Front

What is speed?

Back

Speed is the distance traveled per unit of time, often measured in centimeters per second (cm/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is an insulator?

Back

An insulator is a material that slows down or prevents the transfer of heat.

Front

What is the best insulator among materials?

Back

The best insulator is the material that keeps the temperature stable for the longest time.

Front

What does a graph showing constant speed look like?

Back

A straight line on a distance-time graph indicates constant speed.

Front

What does it mean when a graph is flat?

Back

A flat line on a distance-time graph means the object is not moving.

Front

What is the purpose of testing materials for insulation?

Back

To determine which material keeps temperature changes to a minimum.

Front

How can you tell which candle lasts the longest from a graph?

Back

The candle that has the longest line on a burn time graph lasts the longest.

Front

What is the significance of time in motion graphs?

Back

Time is a crucial factor in determining speed and distance traveled.

Front

What does it mean if an object is slowing down?

Back

It means the speed of the object is decreasing over time.
