Mechanical energy is not valid in which of the following cases? correct answer: A block sliding down a rough inclined plane If the force on an object is doubled, which of the following statements is correct? correct answer: Acceleration is increased by two times. What is the most accurate statement concerning work? correct answer: Work on a system causes a change in the energy of the system. What is the most accurate statement concerning momentum? correct answer: Like other vector q...

What is natural movement in a gravitational field? - correct answerAll objects move in the direction of the g field on their own. Unnatural movement is against the field (when a force is exerted against the field). What is Displacement? - correct answerDisplacement is the change in location of an object. What is Velocity? - correct answerVelocity is the rate of change of displacement (x) v=x/t What is Acceleration? - correct answerAcceleration is the rate of change of velocity (v) a=v/t...

MMET 206 Exam #1 Questions and Answers | Latest Version | 2024/2025 | 100% Pass What is the principle of conservation of energy in mechanical systems? The principle of conservation of energy states that energy cannot be created or destroyed; it can only be transformed from one form to another within a mechanical system. How do you determine the center of gravity for an irregularly shaped object? The center of gravity for an irregularly shaped object can be determined by balancing th...

PHYS 2207 Prelim #2 Exam Questions And Answers 100% Verified. Rotational analogs of all kinematics - answerjust remember can use any of the kinematic equations with the angular quantities as you would use them with linear quantities how many revolutions in that time - answerbe sure to use the kinematic equation involving change in angle and then divide that by 2pi to get revolutions from radians; if you give a final frequency/speed that is not constant likely for these prelim's problems!...

CLASSICAL MECHANICS correct and verified answers(graded A+} real What is friction? - correct answer-Friction works to oppose motion between surfaces, up to some maximum opposing force. - works AGAINST us e.g. wear and tear - works FOR us e.g. keeps car on road -An object will remain in constant motion unless a resultant force acts on it - 1st law=law of inertia - it is not always valid. When it is valid, it is called an inertial reference frame e.g. A plane travels at a constant s...
