Mechanical Forces and Their Effects Quiz

Centripetal force maintains objects in circular motion by continuously pulling them towards the center.

Newton's Third Law asserts that for every action, there's an equal and opposite reaction.

Newton is the unit of force, denoted by 'N'.

Electromagnetic force isn't a mechanical force but rather a fundamental force governing interactions between charged particles.

Friction opposes the relative motion between two surfaces in contact, arising from microscopic interactions.

An object with zero net force maintains a constant velocity according to Newton's first law of motion.

Electromagnetic force isn't considered a mechanical force as it doesn't result from physical contact between objects.

Archimedes' Principle explains buoyancy, stating that the upward force exerted on an object submerged in a fluid equals the weight of the fluid displaced.

Pressure is defined as force per unit area, hence Pressure = Force / Area.

Boyle's Law describes the inverse relationship between the pressure and volume of a gas, holding temperature constant.

Hooke's Law relates the force needed to extend or compress a spring to the distance it is stretched or compressed, illustrating the relationship between stress and strain.

The Reynolds number characterizes flow patterns in fluids, indicating the ratio of inertial forces to viscous forces.

Inertia is the property of an object that opposes changes in its rotational motion, analogous to mass in linear motion.

Plasticity describes the property of materials undergoing permanent deformation when subjected to force, without returning to their original shape.

Power represents the rate at which work is done or energy is transferred, measured in watts (W) or joules per second (J/s).
