Determine Fa, the force applied to the glider by the hanging mass. (Fa = mag; g = 9.8 m/s2 = 980 cm/s2) Analysis Draw a graph showing average acceleration as a function of applied force,
B. C. D. the ratio of the resultant force acting on the body to its acceleration. the ratio of the weight of the body to its acceleration. the amount of matter in the body. the ratio of the gravitational mass of the body to its weight. 11.
Potential Energy - Is the energy stored in an object due to its position in a force field or in a system due to its configuration. 4. Kinetic Energy - An object is the energy that it possesses due to its motion. 5. Friction - Is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
According to the First Law of Thermodynamics, energy cannot be created or destroyed. There-fore, energy is not really lost, but may be released in another form such as heat or light. In this form, the energy may be partly unusable. (p. 28) 25. a. Ca, b. C, c. H, d. Fe, e. N, f. 0, g. K, h. Na (p. 29) 26. a.
b. Find the length of the transverse and conjugate axes. c. Find the slopes of the asymptotes. d. Find the coordinates of the foci. e. Graph the hyperbola.
Weight: force due to the gravity of an object-w=mg 5. Volume: the amount of space that matter occupies, a 3d measure 6. Density: the amount of matter in an object-D=m/v 7. Variable: shorthand way to write a measurement type 8. Unit: tells us how much + what type of measure it is-V=5mph (valid measure) 9.

86. ANS: The wavelength decreases; the amplitude and speed are not affected. 87. ANS: Light undergoes refraction, diffraction, and interference like all waves. Its energy depends on frequency, which is how a particle behaves.
