Static and Kinetic Friction Introduction The amount of friction force between two surfaces in contact depends on the type of the surfaces in contact and the amount of compression between the surfaces. Static friction is the force that is acting against your force before the object begins to move. If you exert a small push on the box‚ the box will not move because static friction is directly opposite to the push. If you apply a greater force than the static friction force‚ the friction increases

Kinetic Theory - Worksheet 1. State three (3) assumptions of the kinetic theory as it relates to gases. [3] ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 2. The kinetic theory assumes that all gases are ideal‚ however‚ this does not exist in reality. a. State the conditions under which gases deviate from ideal behaviour and explain

Learning Goals: • Predict the kinetic and potential energy of objects. • Examine how kinetic and potential energy interact with each other. In the space provided‚ define the following words: Kinetic energy-is the energy of motion. An object that has motion - whether it is vertical or horizontal motion Potential energy-is the energy of an object or a system due to the position of the body or the arrangement of the particles of the system Open Internet Explorer.

Issue: The issue‚ in this case‚ is whether color discrimination was affected by light- skinned and dark-skinned people of the same race. Rule: According to (Moran‚ 2014)‚ color discrimination‚ is based on shade‚ complexion or pigmentation such as dark or light skinned individual. Under Title VII of the Civil Rights Act‚ it is illegal to discriminate of color at the same ethnic group and as well as dissimilar complexions (Moran‚ 2014). Analysis: In this case analysis the facts point out that Walker

Kinetic Molecular Theory Basic Concepts The gas laws developed by Boyle‚ Charles‚ and Gay-Lussac are based upon empirical observations and describe the behavior of a gas in macroscopic terms‚ that is‚ in terms of properties that a person can directly observe and experience. An alternative approach to understanding the behavior of a gas is to begin with the atomic theory‚ which states that all substances are composed of a large number of very small particles (molecules or atoms). In principle‚ the

COLORS “Ding.” That all too familiar tone plays again‚ signaling all marines that are on base and in uniform to snap to the position of attention. At 0800(8:00AM) every day‚ all marines in uniform that are wearing a cover must stop whatever they are doing‚ get to the position of attention‚ and salute to the raising of the American flag. Morning colors is a very significant part of every marine’s day. It is a custom and courtesy that is also one of our many military traditions. Morning and

Part B Now‚ suppose that Zak’s younger cousin‚ Greta‚ sees him sliding and takes off her shoes so that she can slide as well (assume her socks have the same coefficient of kinetic friction as Zak’s). Instead of getting a running start‚ she asks Zak to give her a push. So‚ Zak pushes her with a force of 125 \rm N over a distance of 1.00 \rm m. If her mass is 20.0 \rm kg‚ what distance d_2 does she slide after Zak’s push ends? Remember that the frictional force acts on Greta during Zak’s push and

Kinetic Theory Objectives • Describe how the kinetic-molecular theory is used to explain how gases behave at different temperatures. (Exploration 1) • Analyze data that shows how gas particle mass affects that gas’s behavior. (Exploration 2) • Describe the Maxwell-Boltzmann Distribution. (Explorations 1 and 2) Description of Activity The kinetic-molecular theory states that a collection of gas molecules’ average kinetic energy has a specific value at any given temperature
