7 Science - Lesson 2.1 Average Speed

Front

What is average speed?

Back

Total distance something has traveled divided by the total time it has traveled. S = d/t. Does not identify speed variations during different segments of the trip.

Front

How can you measure average speed in an investigation?

Back

Measure the time it takes for a small toy car or ball to travel a specified distance. Use a distance-time graph or data table to find the average speed.

Front

Define average speed.

Back

Total distance an object traveled divided by the total time it has traveled.

Front

What is displacement?

Back

How far an object has moved from its original position; the difference between the final and initial positions.

Front

What is motion?

Back

An object changes its position; the process of changing position.

Front

Define distance.

Back

The entire length of an object’s path.

Front

What is position?

Back

An object’s distance and direction from a reference point.

Front

What is a reference point?

Back

The starting point you choose to describe the location, or position, of an object.

Front

Define time in the context of motion.

Back

The measurable period during which an action, process, or change occurs.

Front

What is speed?

Back

The distance an object moves per unit of time, such as miles per hour; a measure of the distance an object travels in a given amount of time.
