FLASHCARD QUESTION

Front

Work Noun

[wurk]

Back

Work


The transfer of energy that occurs when a force is applied to an object, causing it to move a certain distance.

Example: This diagram shows the formula for calculating work (W) by multiplying the force (F) applied to an object by the distance (s) it moves.

FLASHCARD QUESTION

Front

Power Noun

[pou-er]

Back

Power


The rate at which work is done or energy is transferred, calculated as the amount of work done per unit time.

Example: A weightlifter applies an upward force (200N) to lift a barbell over a distance (2m), demonstrating the concept of work, a component of power.

FLASHCARD QUESTION

Front

Joule Noun

[jool]

Back

Joule


The standard SI unit of work and energy, equal to the work done by a force of one newton acting over one meter.

Example: An apple weighing 1 Newton is measured on a spring scale. This illustrates the unit of force (Newton), but not the unit of energy (Joule).

FLASHCARD QUESTION

Front

Watt Noun

[wot]

Back

Watt


The standard SI unit of power, defined as one joule of work done or energy transferred per second.

Example: This image shows the formula for power, defining a Watt as the rate of energy use, specifically one Joule of energy used per second.

FLASHCARD QUESTION

Front

Machine Noun

[muh-sheen]

Back

Machine


A device that makes work easier by changing the size or direction of a force, or the distance it acts over.

Example: This diagram shows a pulley system, a simple machine that uses a rope and wheels to lift a heavy weight with less effort (input force).

FLASHCARD QUESTION

Front

Input Force Noun

[in-poot fors]

Back

Input Force


The force exerted on a machine, often by a person or motor, to make the machine perform its function.

Example: This image shows a hand applying an 'Effort' (input force) to lift a 'Load' using a lever and fulcrum, demonstrating a simple machine.

FLASHCARD QUESTION

Front

Output Force Noun

[out-poot fors]

Back

Output Force


The force exerted by a machine to perform a task, which is the result of the input force being applied.

Example: This diagram shows a lever where an applied effort force results in an output force that lifts the load, demonstrating mechanical advantage in a solid system.
