In mechanical systems, energy exists in various forms and can be transferred or transformed to accomplish tasks. Match each mechanical scenario with the primary physical concept it illustrates.
- A compressed coil spring held inside an automotive suspension assemblyElastic potential energy stored due to mechanical deformation
- A heavy flywheel rotating at high speed in a regenerative braking mechanismKinetic energy stored within the motion of a mass
- An electric winch delivering energy to lift cargo at a specified rate per secondMechanical power representing the rate at which work is performed
- A hydraulic cylinder exerting a constant force to slide a steel container across a level floorMechanical work accomplished by applying a force over a displacement
Cevap
Compressed suspension spring matches Elastic potential energy stored due to mechanical deformation; Rotating flywheel matches Kinetic energy stored within the motion of a mass; Electric winch delivering energy per second matches Mechanical power representing the rate at which work is performed; Hydraulic cylinder sliding a container matches Mechanical work accomplished by applying a force over a displacement.
Each scenario directly exemplifies a fundamental physical definition in mechanics: holding a compressed spring stores elastic potential energy, a spinning flywheel stores rotational kinetic energy, rating an output by energy transferred per second defines power, and exerting a force across a distance performs work.
