Speed vs Velocity and Graphs

Front

What is speed?

Back

Speed is a scalar quantity that refers to how fast an object is moving. It is calculated as the distance traveled divided by the time taken.

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position. It includes both speed and direction.

Front

How do you calculate average speed?

Back

Average speed is calculated using the formula: Average Speed = Total Distance / Total 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).

Front

If an object travels 100 meters in 5 seconds, what is its speed?

Back

Speed = 100 meters / 5 seconds = 20 m/s.

Front

What does a flat line on a position vs. time graph indicate?

Back

A flat line indicates that the object is at rest; it is not changing its position over time.

Front

What does a positive slope on a position vs. time graph represent?

Back

A positive slope indicates that the object is moving away from the starting point.

Front

What does a negative slope on a position vs. time graph represent?

Back

A negative slope indicates that the object is moving back towards the starting point.

Front

How can you determine the speed from a distance-time graph?

Back

The speed can be determined by calculating the slope of the line on the graph.

Front

What is instantaneous speed?

Back

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