the variables in this experiment, what type of relationship was being tested? In this experiment, the relationship of the variable force of friction and the coefficient of static and coefficient of kinetic friction are being tested. From the formula:μk=(Ff,k)/Fn, and μs=(Ff,s max)/Fn, the coefficients of friction are equal to the force of friction divided by the normal

INTERPLANETARY DUST AND ORIBITAL DEBRIS Introduction The interplanetary dust particles are sized in between few cm to molecules. The dust particles are charged with +ve charge due to solar wind. The positive charge helps in reacting to the Lorentz force. The interplanetary dust grain population mainly originates in the main asteroid belt that is located between 2 to 4 astronomical units (AU) from the Sun. Dust forms in collisions between bodies of different sizes and energies or may be carried in by

moving? Put the knot at 0,0 and the 3 unit force along the x axis. The 5 unit force goes into the second quadrant 3 units * cos(ᶱ) = + 3 units 5 units * cos(120o) = -2.5 units. Resultant = +3 - 2.5 = 0.5 units. Sum the forces vertically 3*sin(ᶱ) = 0 5*sin(120o) = 4.33 units Resultant + 4.33 vertically Find where you should be. F = sqrt(Fx^2 + Fy^2) F = sqrt(4.33^2 + 0.5^2) F = sqrt(19) F = 4.35 N So you must pull with 4.35 units of force. Now for the angle the angle = 180 +

EXERCISES 15 WORK, ENERGY, AND POWER A. CONCEPTUAL QUESTIONS 1. Is work done when you move a book from the top of the desk to the floor? Why? Yes. It is because the displacement of the book from the top of the desk to the floor and the force that is applied to the book is parallel with one another. 2. State the law of Conservation of Mechanical Energy in two ways? The law of conservation of energy states that energy may neither be created nor destroyed. Therefore the sum of all

it stays in motion until acted upon by an outside force. This is the key element in softball. When the pitcher pitches the ball it travels on the path until the batter hits the ball. The softball travels through the air due to the seams (Bauer & Westfall, Motion of a Softball, 2010). The seams cause high and low pressure fronts while the grip determines how the ball will rotate. Gravity, wind, air drag, velocity, spin, and Magnus are all forces acting upon the softball when it is

SWE is based on the principle of acoustic radiation force. With use of light

angle bending relationship), vicinal to each other (a 1–4 dihedral angle rotation relationship). The nonbonded interactions usually include the following: an exchange repulsion when atoms get too close, a long range attraction arising from dispersion forces, electrostatic interactions coming from the interaction of charges, dipoles, quadrupoles, etc. The exchange repulsion and dispersive attraction combine in what is referred to as a van der Waals term. Sometimes a potential is added to account for hydrogen

estrangement and social isolation. In the three chosen texts; “Enter Without So Much As Knocking” by Bruce Dawe, “Capitalism and Alienation” by Danielle Pioli and “ Be My Brother” by Geneueve Clay, alienation is forced upon the characters by external forces. In the poem “Enter Without So Much As Knocking” by Bruce Dawe, the alienation

coaster is based off the concept of potential energy and kinetic energy. Potential energy is the stored energy of position possessed by an object. Kinetic energy is the energy of motion, whether that is vertical or horizontal motion. Because of the forces of gravity acting on the car and the body both kinetic and potential energy can create the rush that riding a roller coaster can give. The gain of height relates to the gain of potential energy. Thus, the equation for potential energy is PE=mass*gravity*height
