Front

What is speed?

Back

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

Front

How can we determine which object is moving faster?

Back

By comparing the time it takes for each object to travel the same distance; the one that takes less time is faster.

Front

What does it mean when an object speeds up?

Back

It means the object's speed is increasing over time.

Front

What is a constant speed?

Back

Constant speed means an object travels the same distance in equal intervals of time.

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

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

Back

A steeper slope indicates a higher speed.

Front

What is the significance of a flat line on a distance-time graph?

Back

A flat line indicates that the object is not moving (at rest).

Front

If Tamara runs a distance in 45 seconds and Justin in 52 seconds, who is faster?

Back

Tamara is faster because she took less time to cover the same distance.

Front

What does it mean if an object slows down?

Back

It means the object's speed is decreasing over time.
