Understanding Acceleration and Velocity Graphs

The video tutorial by Miss Gosling covers graphing techniques to analyze motion graphs for accelerating objects. It explains how to determine acceleration using velocity vs. time and position vs. time graphs. The tutorial also discusses how to identify positive and negative acceleration by analyzing graph slopes. Students are encouraged to apply these concepts through an extra credit opportunity.

What is the formula for acceleration?

• Change in velocity over time

• Velocity times time

• Distance divided by time

• Speed minus time

In a velocity versus time graph, what does a horizontal line indicate?

• Constant acceleration

• Zero acceleration

• Increasing velocity

• Decreasing velocity

How can you tell if an object is accelerating using a position versus time graph?

• The graph is a straight line

• The slope of the graph is changing

• The graph is horizontal

• The graph is vertical

What does a positive slope in a position versus time graph indicate?

• Constant velocity

• Zero velocity

• Positive velocity

• Negative velocity

If a graph's slope is decreasing but remains negative, what can be said about the acceleration?

• Velocity is constant

• Acceleration is negative

• Acceleration is positive

• Velocity is zero

What does it mean if all tangent lines on a graph are going uphill?

• Negative velocity

• Positive velocity

• Zero velocity

• Constant velocity

In a velocity versus time graph, what does a steep slope indicate?

• High acceleration

• Constant velocity

• Low acceleration

• Zero acceleration

What happens to velocity if acceleration is negative?

• Velocity decreases

• Velocity remains constant

• Velocity increases

• Velocity becomes zero

What is indicated by a non-horizontal line in a velocity versus time graph?

• The object is decelerating

• The object is moving at constant speed

• The object is at rest

• The object is accelerating

How can you determine the sign of acceleration from a graph?

• By checking if the slope is increasing or decreasing

• By measuring the length of the graph

• By counting the number of lines

• By looking at the color of the graph
