Scholar Start 12/9/13Generals Can: Reevaluate what they know about the acceleration formula on an IKTB quiz

Solve the following problems to practice

before your quiz! 1. What is the acceleration of a 7 kg mass being pulled by a 56 N force?2. A motorcycle traveling at 25 m/s accelerates at a rate of 7.0 m/s2 for 6.0 seconds. What is the final speed of the motorcycle?

During the IKTB Quiz

• Voice level zero• Do all your own work• Fill in the IKTB boxes! • Try, even if you think you don’t know!

1. As you finish, turn them in to the blue organizer. 2. Then grab the individual assignment off the counter to

begin working silently until everyone else is finished.

Work independently on your study guide until everyone is finished.

Scholar Start 12/10/13Generals Can:Explain friction as a force that resists change in motion.

Identify and explain 4 different types of friction based on the pictures below.

Friction:1. Rolling Friction: the force resisting the motion

when a body (such as a ball, tire, or wheel) rolls on a surface.

2. Sliding Friction: the kind of friction that is caused by two surfaces that slide against each other

3. Fluid Friction: occurs between layers within a fluid that are moving relative to each other

4. Static Friction: is the friction that exists between two or several solid objects that are not moving relative to one another

A fluid can be a GAS or a LIQUID

How is air resistance considered friction? Which

type of friction is it?

Think-Pair-Share:

Parachute Guidelines: • Provided thread, Kroger bags, tape, and quarters• Quarter must stay safely in the “basket” • “basket” cannot have a height higher than an inch,

and edges cannot touch the quarter. • Cannot use the bag “as is”

*make your design intentional! You must be able to explain why you chose your design, using Motion and Forces content vocabulary*
