Happy Tuesday!DQ: What is the velocity of a snail that can slither 10 feet in 30 minutes? What are the units of measure for this velocity? What is that velocity in feet per hour?

Today:Energy Transformation Project Gallery Walk

Review Force and Motion Vocabulary

• DQ: What is the velocity of a snail that can slither 10 feet in 30 minutes? What are the units of measure for this velocity? What is that velocity in feet per hour?

• v = distance/time• v = 10ft/30min• v = 0.33 ft/min• Since there are 60 minutes in an hour and the

snail will go 0.33 ft in 1 minute• We multiply 0.33 ft/min by 60 minutes to get• 20 ft/hr

Gallery Walk

• Please place your completed visual on your table with your assignment handout

• Look at the visuals created by your classmates• Identify and describe an energy transformation • List a strength of the visual • Offer a suggestion for improvement

What to turn in

• The visual • The project handout (white – title: Energy

Transformation Project)• The written portion – through google

classroom DID YOU CLICK Turn-In in the upper right?

Some Definitions• Force: a push or a pull on an object because of

its interaction with another object• Gravitational force: The force of attraction

between all masses in the universe• Frictional force: the force that resists the

motion of an object• Applied force: a push or pull on an object by a

person or by another object• Normal Force: a force that prevents objects

from falling forever

Free Body Diagrams

• A way to show forces• Includes only the forces acting on an object• Called a “free” body because you only show

the object, not its surroundings (so it is “free” of its environment)
