PS.5.2.2 — Measuring Motion and Using Graphs

What does a steeper line on a graph tell us about speed?

• The steeper the line, the slower the object is moving.

• The steeper the line, the faster the object is moving.

• The steeper the line indicates no change in speed.

• The steeper the line shows the object is at rest.

What is speed?

• The rate at which an object changes its position.

• The distance traveled by an object in a given time.

• The measure of how fast an object is moving—distance divided by time.

• The total distance covered by an object regardless of time.

What does a flat (horizontal) line on a distance/time graph mean?

• The object is moving at a constant speed.

• The object is accelerating.

• The object is not moving—it has stopped.

• The object is moving backwards.

What do the X and Y axes represent on a distance/time graph?

• X-axis = distance; Y-axis = time.

• X-axis = speed; Y-axis = distance.

• X-axis = time; Y-axis = distance.

• X-axis = distance; Y-axis = speed.

How can you compare the speeds of two objects?

• Measure the weight of each object.

• Measure how far each travels in the same amount of time or how long each takes to go the same distance.

• Observe the color of each object.

• Count the number of times each object moves in a minute.

What does a distance/time graph show?

• It shows how far an object moves over a period of time.

• It shows the speed of an object at a specific moment.

• It shows the direction of an object's movement.

• It shows the acceleration of an object over time.

On a graph, what does a straight line going up mean?

• The object is moving at a steady speed.

• The object is accelerating.

• The object is at rest.

• The object is moving at a variable speed.

How can you measure motion?

• By measuring how far something travels in a certain amount of time.

• By counting the number of objects in motion.

• By observing the color of the moving object.

• By estimating the speed based on visual perception.

What is motion?

• A change in an object's position over time.

• A force acting on an object at rest.

• The speed of an object in a straight line.

• The distance traveled by an object in a given time.
