ADV 12/2 Speed and Graphs

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in units like km/hr or mi/hr.

Front

How do you calculate speed?

Back

Speed = distance/time (distance divided by time).

Front

What is the unit of speed?

Back

Common units of speed include kilometers per hour (km/hr) and miles per hour (mi/hr).

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that shows equal distance covered in equal time intervals.

Front

What does a stationary object mean in a graph?

Back

A stationary object is represented by a horizontal line on a graph, indicating that the object is not moving.

Front

What is the formula for calculating distance?

Back

Distance = speed x time (distance equals speed multiplied by time).

Front

What does it mean when an object is increasing speed?

Back

Increasing speed means the object is accelerating, shown by a curve that slopes upwards on a graph.

Front

What does it mean when an object is decreasing speed?

Back

Decreasing speed means the object is decelerating, shown by a curve that slopes downwards on a graph.

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 is a speed-time graph?

Back

A speed-time graph shows how speed changes over time, with speed on the vertical axis and time on the horizontal axis.
