Chapter 13 Review

Front

What is a wedge in simple machines?

Back

A wedge is a simple machine that consists of two inclined planes joined together, used to separate objects or hold them in place.

Front

What is a pulley and how does it work?

Back

A pulley is a simple machine that consists of a wheel on an axle or shaft designed to support movement and change the direction of force.

Front

What is the unit of measurement for work?

Back

The unit of measurement for work is Joules.

Front

What is the ideal mechanical advantage of a pulley?

Back

The ideal mechanical advantage of a pulley is the ratio of the load force to the effort force, indicating how much easier the machine makes the work.

Front

Why do workers use an inclined plane?

Back

Workers use an inclined plane because it makes their work easier by requiring less effort to lift heavy objects.

Front

What is the definition of work in physics?

Back

Work is defined as the product of force and the distance over which that force is applied, measured in Joules.

Front

What is the difference between effort and load in simple machines?

Back

Effort is the force applied to a machine, while load is the weight or resistance that the machine is working against.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects with less effort.

Front

What is the function of a lever?

Back

A lever is a simple machine that uses a fulcrum to lift or move loads with less effort.

Front

What is mechanical advantage?

Back

Mechanical advantage is the factor by which a machine multiplies the force put into it, making work easier.
