Motion & Velocity

Fill in these notes to summarize our learning about motion graphs.

Practice reading the graph. The graph shows a snail's wild journey through a garden. Match the three sections of the graph above with the description of the snail's motion during that time period.

Draggable item		Corresponding Item
speeding up		A
not moving / speed = 0		B
travelling at a constant speed		C

How fast was the snail moving from 6-9 minutes? Include units in your answer!

Let's make sure we all understand the science vocab for these graphs. As you watch the video below, pause to match each description with the definition: Speed, Velocity or Acceleration?

The rate at which an object changes position, or distance / time.
Examples: 70mph, 5m/sec
Speed plus direction

Calculate. A bowling ball moves 18 meters every 2 seconds down the lane at a bowling alley. What is the speed?

Draw a graph that tells this story:
A gazelle walks towards the river at a steady velocity 1m/second for 10 seconds. She stops to drink for 5 seconds, then sees an alligator. She turns around and accelerates, covering 10 meters in 5 seconds. (The graph shows the gazelle's starting position. Please add axis labels, units and a line to show her motion.)

The four graphs show distance over time. Match: what car motion would create each graph?

Read to review the ideas, and answer questions 1-4.

An object can have velocity without acceleration.

Put it all together. Here is a made-up time v. distance graph. The blue line shows one traveler and the red line a second. Explain what is taking place with as much detail as you can. Include the words "speed" "velocity" and "acceleration" in your story.

This Porsch can accelerate from 0 to 60 mph in 2.2 seconds.
Meanwhile, this Nissan SUV takes over 10 seconds.

When we build a car for this unit, a goal will be to design a car that can move far and fast. Next week, we'll be talking about what that might involve. Below, guess three different reasons a car might be able to accelerate faster.

Submit! Here are choices when you are done: 
- Play the stickman game some more.
- This challenging game is similar but involves designing ramps for a rolling ball. 
- Go to Canvas "Done Do's" (from the bottom of the homepage) and choose an activity.

Draggable item		Corresponding Item
3		Parked, still
2		Driving forward at a steady pace
Not shown above		Accelerating
4		Decelerating
1		Driving backwards

Pushing on the gas peddle causes: (choose all that are correct)

Your car's speedometer says "25mph." What "point of reference" is being used?

Opinion: is it ever okay to drive at a velocity higher than the posted speed limit?
