This test covers Work, mechanical energy, kinetic energy, potentialenergy (gravitational and elastic), Hooke’s Law, Conservation of Energy, heat energy, conservativeand non-conservative forces, with some problems requiring a knowledge of basic calculus.
Study with Quizlet and memorize flashcards containing terms like Work: W = Fdcosθ, Kinetic Energy: K= (1/2)mv^2, Net Work/The Work-Energy Theorem: Wnet = ((mv^2)/2) - ((mv0^2)/2) and more.
Free practice questions for AP Physics 1 - Work, Energy, and Power. Includes full solutions and score reporting.
FACT: Equations for different forms of energy (unit = N.m or J). Kinetic energy: KE = ½mv2. Here, m is the mass of the object, and v is its speed. Gravitational potential energy: PE g = mgh (or U g) Here, m is the mass of the object, g is the gravitational field, and h is the vertical height of the object above its lowest position.
problems and physics teachers may present slightly different methods and/or different symbols and variables in each topic, but the underlying physics concepts are the same and we ask you read the solutions with an open mind and use these differences to expand your problem solving skills.
P=∆E/t. power given force. P=Fvbarcosθ. Study with Quizlet and memorize flashcards containing terms like work, kinetic energy, net work and more.
I. The frame of reference of any problem is assumed to be inertial unless otherwise stated. II. Assume air resistance is negligible unless otherwise stated. III. In all situations, positive work is defined as work done on a system. IV. The direction of current is conventional current: the direction in which positive charge would drift.
