VT and PT Graphs

PT and VT Graphs

Poll

Last week we calculated Speed, Velocity, and Acceleration. How comfortable do you feel now about making those calculations?

Review Position vs Time graphs

This type of graph shows the change to object's position over time.

The slope of a PvT graph represents Velocity.

Multiple Choice

What is happening to the object according to this graph?

• Nothing, it is not moving.

• Constant positive velocity

• Positive acceleration

• Negative acceleration

Velocity vs Time Graphs

• VT Graphs are another way to graph motion.

• VT Graphs show the change to an object's velocity over time.

• The slope of a VT Graph represents Acceleration.

Multiple Choice

The slope of a VT Graph represents what?

• Velocity

• Time

• Acceleration

• What I ate for breakfast.

Positive VT Graph

VT Graphs show positive motion whenever the line for the graph is above the "0" line.

Any line above the "0" line means the object IS in motion.

Flat line means constant velocity.

"Slanted" line means acceleration.

Multiple Choice

Is the object in the following graph Accelerating?

• Yes

• No

• No way to know based on the graph.

Negative VT Graph

VT Graphs show negative motion whenever the line for the graph is above the "0" line.

Any line below the "0" line means the object IS in motion.

Flat line means constant velocity.

"Slanted" line means acceleration.

Multiple Choice

Is the object in the following graph accelerating?

• Yes

• No

• No way to know based on the graph.
