Motion Position and Frame of Reference Unit Standards

Motion, Position, and Frame of Reference

Unit Standards 5. P. 5 A. 1 Use mathematical and computational thinking to describe and predict the motion of an object (including position, direction, and speed). 5. P. 5 A. 2 Develop and use models to explain how the amount or type of force (contact and non-contact) affects the motion of an object. 5. P. 5 A. 3 Plan and conduct controlled scientific investigations to test the effects of balanced and unbalanced forces on the rate and direction of motion of objects. 5. P. 5 A. 4 Analyze and interpret data to describe how a change of force, a change of mass, or friction affects the motion of an object. 5. P. 5 A. 5 Design and test possible devices or solutions that reduce the effects of friction on the motion of an object.

What is Motion? • Motion is movement • Think about vehicles and what causes them to move. Think about how engineers design vehicles. Throughout this unit you will design, build, and test your ideas.

What is Motion? 1. Write about how vehicles move. 2. Write about how to design vehicles. Whole class brainstorming session 3. Write about what you want to find out about motion and design.

What is Motion • Working with your group, design a vehicle that will move 100 cm (39 in) in 20 minutes. • How will you test whether your vehicle will meet the requirement?

What is Motion? True or False? Motion describes a push or a pull.

What is Motion? Answer in your notebook: • How did you get your vehicle to move? • What was one problem your group encountered while building the vehicle? • How did you solve the problem?

What is Motion • What is one thing you are excited to learn about in this unit?

What is Motion?

Motion • What is motion? • A change in the position of an object over time. • How do you know something is in motion or has moved? • You use a reference point! • A stationary (not moving) object such as a tree, street sign, or a line on the road. Did the beaver move?

What is motion? • Motion of an object has two parts: distance and direction. • Distance is the length the object moved. It can be measured in meters, kilometers, feet, or miles. • Direction is location of the new position relative to the old position. We use words like north, south, east, or west. To measure direction we use a compass or protractor and units of degrees.

What is motion? • Position- the location of an object. It answers the question, “where is the object? ”

What is motion? • Frame of reference- a way to describe the motion of an object by comparing the moving object to an object that is in a fixed position. • Almost anything can be a frame of reference.

You are observing a hen and her babies. The young birds are (below/above/behind) the hen.

You are at the Jungle Terrace at the Nashville Zoo. In which direction must you travel in order to reach the Gibbon Islands exhibit?

Which island is farthest west? Which island is farthest south?

Compare & Contrast Suppose you are walking down the aisle of a moving train. How would your motion appear different to a person sitting on the train than to a person standing outside the train? https: //www. effinghamschools. com/cms/lib 4/GA 01000314/Ce
