What is a simple machine?

Back

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

Front

What is mechanical advantage?

Back

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

Front

What is the formula for calculating mechanical advantage using forces?

Back

Front

What is the trade-off when using simple machines?

Back

When using simple machines, the trade-off is that while the force needed to move an object is reduced, the distance over which the force must be applied is increased.

Front

What is resistance in the context of simple machines?

Back

Resistance is the force that opposes the motion of an object. In simple machines, it is the load that needs to be moved.

Front

What is effort in the context of simple machines?

Back

Effort is the force applied to a simple machine to move a load or overcome resistance.

Front

What is the equivalent resistance in a circuit?

Back

Equivalent resistance is the total resistance of a circuit when resistors are combined in series or parallel.

Front

What is the formula for calculating equivalent resistance in series?

Back

Front

What is the formula for calculating equivalent resistance in parallel?
