Basic Motion with Mrs. Williams

• Motion is a word to describe a moving object.
• A moving object is either moving in uniform or non-uniform motion.
• Uniform motion is steady and consistent.
  • With uniform motion, a moving object does not speed up, slow down, or change direction.
  • If you are traveling in uniform motion, you will not be able to feel the effects.
  • If you try to be absolutely motionless your body will still be rotating on the planet orbiting around the sun, orbiting around the galactic center of the Milky Way, and racing across the cosmos at several hundreds of thousands of miles per hour.
  • This motion is practically uniform, so you don’t feel its effects.
• Non uniform motion happens whenever an object changes its motion.The easiest way to differentiate between uniform and non-uniform motion is that you can feel the effects of one and not the other.
  • The three factors that affect non-uniform motion are: speeding up, slowing down, and changing direction of motion.
  • You can feel the effects of non-uniform motion.
  • Every time you speed up, slow down, or turn in a car your body will move in the opposite direction to the change in motion.
• Whenever an object moves, this really means it movesrelative to something else.
  • A car moves relative to the street.
  • A bullet moves relative to a gun.
  • A train moves relative to the tracks.
  • The moon moves relative to the earth.
  • The earth moves relative to the moon.
• The perspective from which motion is observed is called a frame of reference.
  • Any frame moving in uniform motion is called an inertial reference frame.
  • Any frame moving in non-uniform motion is called a non-inertial reference frame.

Why is uniform and non-uniform motion important for students?

• Perfect uniform motion does not truly exist.
• The entire universe is interconnected; every object exerts a force onto another object.
• Even an asteroid floating in the farthest reaches of outer space will be pulled by a weak force of gravity from all the other objects in the universe.
• This is important for students to know because the forces of nature connect all objects.
• We may set boundaries as individuals, as states, or as nations; however, we are all connected.

Inquiry Lab I:

Have class watch the following videos, in part or in whole.  (You may use different videos if you would like; these are just suggested so you have something to show the students.)  After each one, have students describe the motion in the videos.  The following questions may help:

1. What is moving?
2. Is the object’s motion changing?
3. If so, how?  For example, is its direction changing?  Is it speeding up?  Is it slowing down?

1. Uniform vs. Non-Uniform Motion Presentation

Challenge students to brainstorm different types of scenarios that involve motion. Have students come up with 5 examples of uniform motion and 5 examples of non-uniform motion. Students should make either a poster or a brochure that explains the difference between uniform and non-uniform motion and includes the 5 examples of each they have brainstormed. Their poster or brochure should include important vocabulary and pictures for each of the examples.

If time allows, have students present their poster or brochure to the class.

2. Venn Diagram

Students independently come up with an example of uniform motion and an example of non-uniform motion. Students then create a Venn diagram to compare and contrast their examples. Once students have created their Venn diagram, they should write a paragraph that compares their examples of uniform and non-uniform motion.

3. End of Class Assessment: Demonstration of Learning/Exit Ticket

a. Describe the difference between uniform and non-uniform motion.

b. Give two examples of uniform motion and two examples of non-uniform motion.

c. Extended Thinking: Why do scientists use uniform motion when calculating motion even if true uniform motion does not exist in our universe? Answer in the form of a paragraph. 

Engagement Questions: How is motion important to your everyday life? Has anyone ever been in any type of accident, whether just falling down or in a vehicle? Would accidents happen if objects weren’t in motion? If you are in a closed box on a train, is there any test you can conduct to determine how fast you are traveling without looking outside? What direction will your body lean if you are in a car turning left? Why? When will you feel your body push to the back of your seat while traveling in a car? When you are in motion, do you always feel your body push to the back of a seat? If you are in a traveling car and you throw a ball into the air will the ball fly back and hit you in the face? Why or why not? No, because it is still in motion with the traveling car. Why does a ball keep moving after you throw the ball?  An object in motion tends to stay in motion.  Why is it more difficult to ride a bicycle up a hill than across a flat plane?
