Physical Science Review

Which graph represents constant velocity?

• A

• B

• C

• D

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

When you have a P v T (position vs. time) graph, how do you find the speed of the object at a certain time?

• Read it off the y-axis

• Calculate the slope

• Find area under the graph

• You don't because you can't

When you have a P v T (position vs. time) graph, how do you find the position of the object at a certain time?

• Read it off the y-axis

• Calculate the slope

• Find area under the graph

• You don't because you can't

When you have a V v T (velocity vs. time) graph, how do you find the speed of the object at a certain time?

• Read it off the y-axis

• Calculate the slope

• Find area under the graph

• You don't because you can't

When you have a V v T (velocity vs. time) graph, how do you find the displacement that the object traveled?

• Read it off the y-axis

• Calculate the slope

• Find area under the graph

• You don't because this graph only shows you the object's velocity

Check all that apply: Velocity is...

• the speed at which an object moves in a certain direction

• displacement over time

• Δd/Δt

• the slope of a P v T graph

• the slope of a V v T graph

What the first step when you're looking at a graph problem?

• 
• Just look at the behavior of the line

• 
• Read the y-axis

Which V v T graph matches this P v T graph?

• 
• 
• 
• 

The following graph shows the amount of dollars earned as a function of hours worked. What is the slope of the graph (in other words, how much money is earned per hour)?

• $63 per hour

• $63 per 2 hours

• $100 per hour

• $200 per 3 hours
