3. Wednesday, Dec. 16th 3 Bell-ringer: Get out your notebooks and folders. Agenda: Bell-ringer Complete “Motion and Forces” notes Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects. (S.7.PS.6) Plan an investigation to provide evidence that the change in an objects motion depends on the sum of the forces on the object and the mass of the object. (S.7.PS.7) Objective:

5. Write title on page 53, “Motion and Forces” Force– a push or pull applied to an object Net Force– when two or more forces act on an object at the same time. WRITE AND DRAW EVERYTHING!

6. Friction– the force that opposes the sliding motion of two touching surfaces. – Friction is caused by microscopic bumps on surfaces called micro-welds. WRITE DOWN EVERYTHING! Types of FrictionDescriptionExample StaticFriction in which two surfaces are not moving past each other. Pushing a fridge across a floor. SlidingFriction where two surfaces slide past one another. Sledding down a hill. RollingFriction between a rolling object and surface it rolls on. Skateboard moving on ground. FluidFriction when object moves through fluid; meaning either a liquid or gas. Skydiving

7. Air Resistance– friction-like force that opposes motion of objects that move through air; depends on speed, size and shape of object. WRITE AND DRAW EVERYTHING!
