PSci Unit 9 & 10- Work, MA, Simple Machines, and Waves

Front

What is the formula that relates wavelength and frequency?

Back

λ = c/f, where λ is wavelength, c is the speed of light, and f is frequency.

Front

What is the speed of light in meters per second?

Back

3.0 x 10^8 m/s.

Front

What is an example of work in physics?

Back

Picking up a box is an example of work.

Front

What is an inclined plane?

Back

A flat sloping surface that connects lower and higher elevations, making it easier to raise objects.

Front

How does resistance distance affect the mechanical advantage of a lever?

Back

Longer resistance distance decreases mechanical advantage.

Front

What is the definition of mechanical advantage?

Back

Mechanical advantage is the ratio of the output force to the input force in a machine.

Front

What is the work done when you throw a baseball a distance of 20 meters?

Back

Work is done when you throw a baseball a distance of 20 meters.

Front

What is the relationship between work, force, and distance?

Back

Work = Force x Distance.

Front

What is a simple machine?

Back

A simple machine is a device that changes the direction or magnitude of a force.

Front

What are the six types of simple machines?

Back

Lever, inclined plane, wedge, screw, pulley, and wheel and axle.
