In a distance v time graph, what does the slope show?

The speed

In a speed v time graph, what does the slope show?

The acceleration

In a distance v time graph, if the line is horizontal (parallel to the time), what is happening?

No distance is being traveled, or the object has stopped moving

The object is traveling at a constant speed.

What does this graph show?

The object is coming back.

What does this graph show?

The object is stopped.

What does this graph show?

The speed of the object is decreasing.

What does this graph show?

Steady Speed

What is the space between points A and B showing?

Stopped

What is the space between points B and C showing?

Accelerating

What is the space between points C and D showing?

Decelerating

What is the space between points D and E showing?

Return to start

What is the space between points E and F showing?

meters (m)

Unit for distance

Seconds (s)

Unit for time

Meters/second (m/s)

Unit for speed

Meters/second/second (m/s^2)

Unit for accleration

velocity

Speed in a given direction

velocity= distance/time (v=d/t)

equation for average speed

v=(d2-d1)/(t2-t1)

equation for speed between two points

acceleration= velocity/time (a=v/t)

equation for acceleration

acceleration

The rate at which velocity changes
