How fast is that object moving?

​How fast is an object moving?

Learning Outcomes

1. I can describe the differences and similarities between speed and velocity.

2. I can predict how velocity changes as the distance changes.

3. I can predict how velocity changes as the time interval changes.

​One dog moving different directions along a path during the same amount of time.

Model 1

​Work on Model 2 questions #22-25.

Multiple Choice

25. When $$\Delta t$$   remains constant, as the magnitude of $$\Delta s$$   increases, the magnitude of the velocity

• decreases

• remains the same

• also increases

One dog with the same magnitude of displacement during different time intervals

Model 3

​Work on Model 3 questions #26-31.

Open Ended

29. What is the manitude of velocity in trial 13? Trial 14?

Multiple Choice

• decerases

• remains the same

• also increases

​Work on Model 3 questions #32-35.

Multiple Choice

If an object moves for a greater amount of time, but has the same displacement, what will happen to the object’s average velocity?

• Average velocity will decrease.

• Average velocity will increase.

• Average velocity will remain the same.

• You cannot tell from information given.

Open Ended

What do you still wonder?

Write one additional question you have about average speed, direction, displacement, or average velocity.

Poll

How confident are you regarding the following learning objectives:

1. I can describe the differences and similarities between speed and velocity.

2. I can predict how velocity changes as the distance changes.

3. I can predict how velocity changes as the time interval changes.

• I can do all 3 really well.

• I can do all 3 but I am sill a bit confused.

• I am really confused.

• I don't know what is going on.
