Introduction. high-resolution type of scanning probe microscopy, with demonstrated resolution of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. . How It Works. viscosity. : a liquid’s resistance to flow . -- high viscosity = . high resistance to flow . -- depends on IMFs . -- . as temp. increases, viscosity decreases . Molecules on a. liquid’s surface . Here’s Tim & Mobey on Force. Brainpop. Suppose I asked you to move a heavy desk in the classroom. How would you move it? . hmmmmmmmmmmm...... You might get on one side of the desk and start pushing, Or you might grab the legs and start pulling. . Newton’s Laws. Isaac Newton. The man, myth, the legend…while you spend your time on Facebook, Newton spent his studying the behavior of objects in MOTION.. His conclusion…anything in motion is going to follow 1 of the 3 basic . ● .

Slappey. Ms.Carter. 5. th. Grade. December 1, 2015. What are Constructive Forces?. Constructive Forces are processes that help build or construct the Earth.. Constructive forces can deposit soil or silt in a river.. Robert Strawn. Compiled 10/16/11. A force is any push or pull that one object exerts on . another that causes a change in motion, direction, or shape.. The unit for force is the Newton (N) and is equal to . Chemistry 11. Ms. McGrath. Intermolecular Forces. The forces that bond . atoms. to each other within a molecule are called . intramolecular forces. . Covalent bonds and ionic bonds are an example of intramolecular forces.. Forces. Forces can be thought of as pushes and pulls. Examples. You exert a force on a door to open it (a push). Gravity exerts a force on you which holds you to the surface of the earth (a pull). Forces. What is pressure?. Pressure is the force per unit area that is applied on the surface of an object.. Chapter 12: Forces and Fluids. Calculating pressure. Pressure increases if the force applied increases and decreases if the area of contact increases.. What is a force?. A force is a push or a pull. . Forces make objects accelerate. What are the two general types of forces? How are they different?. Type 1: Contact Forces. Force as a result of object touching. At surface, some forces are missing, pulls molecules down and together, like membrane exerting . tension. on the . surface. Pressure increase is balanced by surface tension, . s. . surface tension = magnitude of tension/length.
