by teacher candidates as part of the EDCP 357 physics methods courses at UBC. An 8 kg block is launched from point A to point B over a rough surface. As the block passes point B, it has slowed down to a velocity of 4.0 m/s and it has generated 36 J of heat energy.
This test covers Work, mechanical energy, kinetic energy, potential energy (gravitational and elastic), Hooke’s Law, Conservation of Energy, heat energy, conservative and non-conservative forces, with some problems requiring a knowledge of basic calculus. Part I. Multiple Choice 1.
This is the first of two workbooks full of challenging physics problems designed to help you prepare for the Oxford Physics Aptitude Test (PAT). The two workbooks contain many questions of varying difficulty and subject
Use work and energy principles to calculate a speed or a height or an energy value. Most problems include little to no little scaffolding. Includes 10 problems.
FACT: Conservation of Energy- the internal energy of a system includes the kinetic energy of the objects that make up the system and the potential energy of the configuration of the objects that make up the system.
To understand energy and conservation of energy, we must first define some terms: work, kinetic energy (KE), and potential energy (PE). We’ll get to PE in the next Chapter.
Problems: Work, Energy, Power 1) A 10.0 kg mass sliding on a frictionless horizontal surface at 7.00 m/s hits a spring that is attached to a wall. The spring has a spring constant of 5000 N/m. a) Determine the maximum compression of the spring. At maximum compression, the box has a speed of zero.
