What is a simple machine?

Back

A simple machine is a device that changes the direction or magnitude of a force, making work easier. Examples include levers, pulleys, and inclined planes.

What is power in physics?

Back

Power is the rate at which work is done or energy is transferred, measured in Watts (W).

Front

How do you calculate power?

Back

Power (P) can be calculated using the formula: P = Work (W) / Time (t).

Front

What is mechanical advantage?

Back

Mechanical advantage is the ratio of the output force to the input force in a machine, indicating how much a machine multiplies force.

Front

What is the formula for mechanical advantage of a lever?

Back

Mechanical Advantage (MA) = Length of effort arm / Length of resistance arm.

Front

What is the IMA of a pulley system?

Back

The Ideal Mechanical Advantage (IMA) of a pulley system is equal to the number of rope segments supporting the load.

Front

What is a wheel and axle?

Back

A wheel and axle is a simple machine consisting of a larger wheel attached to a smaller axle, used to lift or move loads.

Front

What is the unit of measurement for work?

Back

The unit of measurement for work is the Joule (J), which is equal to one Newton meter.

Front

What is a pulley?

Back

A pulley is a simple machine that consists of a wheel with a groove around it, used to change the direction of a force and lift loads.

Front

What is the difference between IMA and AMA?

Back

IMA (Ideal Mechanical Advantage) is the theoretical advantage without friction, while AMA (Actual Mechanical Advantage) is the advantage considering friction.
