Physical Science

Units serve as guides to a specific content or topic location. Nested under devices are lessons (in purple) and hand-operated tasks (in blue).

You are watching: To what angle does the pendulum swing on the other side?

Note that not all lessons and also tasks will certainly exist under a unit, and instead might exist as "standalone" curriculum.

pendulums made clocks possible


Students explore just how pendulums work and why they are advantageous in daily applications. In a hands-on activity, they experiment with string size, pendulum weight and angle of release. In an connected proficiency task, students check out the mechanical principle of rhythm, based on the principle of oscillation, in a wider organic and also social conmessage — in dance and sports, poeattempt and other literary develops, and interaction in basic.

Engineering Connection

Engineers understand that understanding the physics of exactly how pendulums behave is an important action towards expertise all kinds of motion. Many type of other objects relocate earlier and forth consistently choose pendulums, such as a weight bouncing up and also dvery own on a spring, and also the earlier and forth movement of radio waves. In enhancement to using pendulums in clocks, engineers usage them to detect earthquakes, meacertain exactly how fast a bullet is flying, aid structures to withstand earthquake shaking and assist robots balance. In Taiwan"s resources city, the Taipei 101 skyscraper has actually a huge 726-ton pendulum suspended over the 88th floor to counteract winds, reducing the building"s sway and keeping movement sickness at bay.

Learning Objectives

After this lesson, students need to be able to:

Exsimple exactly how weight, length and also angle of swing affect the period of a pendulum.Relate the examine of physics and Galileo"s experiments with the creation of clocks.Describe how the conservation of momentum relates to pendulums.Give examples of how designers usage pendulums.

Educational Standards

Each lesboy or activity is associated to one or even more K-12 science, modern technology, design or math (STEM) educational criteria.

All 100,000+ K-12 STEM standards extended in are collected, maintained and also packaged by the Achievement Standards Network (ASN), a project of D2L (

In the ASN, requirements are hierarchically structured: initially by source; e.g., by state; within source by type; e.g.
