Students learn more about forces by examining the force of gravitational attraction. They observe how objects fall and measure the force of gravitational attraction upon objects.

In this hands-on inquiry activity, students will design and construct an apparatus that will permit an egg to survive a nine foot fall. Students are given limited materials, so they must critically think about the design and improvise strategies during the building of the apparatus

This lab exercise involves small teams of 3-4 students working to collect a profile of gravity measurements over a topographic feature. There is a slope break on our campus where this exercise is done, but any fairly prominent topographic feature will suffice. The students make several measurements with the gravimeter, and collect their own topographic data using meter-tapes and hand-levels although a GPS unit could also be used. The students then convert the meter readings into relative gravity measurements, and make graphs using several different assumed densities. This exercise gives the students practice in collecting field data, analyzing numerically and graphically, and understanding theoretical concepts.

This text includes 25 reading assignments for an introductory astronomy course. They have been modified from the OpenStax Astronomy 2e and College Physics 2e (linked in related resources below) textbooks to order the topics in a logical manner for a one semester course and provide shortened (~10-20 pages) readings intended for biweekly reading assignments. The text also features enhanced treatment of the Newton's Laws, Energy, and Optics content that go beyond the typical introductory astronomy course for non-majors.
Course connections: This content was built for an introductory survey of astronomy course (e.g., PHYS 103), including apparent motions of objects in the sky, light, telescopes, solar system objects, exoplanets, the sun, stars, galaxies, and cosmology. Basic math skills (arithmetic, powers, scientific notation, unit conversions) will be used frequently. This course is designed for students in all majors.

This activity is a field investigation where students will gather data on speed, acceleration, gravity, friction, and forces. They will design and conduct an investigation.

This physics activity is a projectile motion / gravity investigation where students drop and shoot (horizontally) soft balls from different heights and record the time taken to hit the ground. Students make a trendline to predict the time it will take the ball to hit the ground from a certain height. Students will also discover that shot and dropped balls hit the ground at the same time.

Students use media resources and an in-class investigation to explore the types of energy within different types of systems. They also use the formulas for kinetic and potential energy to examine the path of a projectile.

In this physics interactive lecture demonstration, students will investigate the effects of acceleration due to gravity in a number of different situations using a plastic water bottle. Based on an original activity from Peter Hopkinson, AAPT.

How do we communicate with each other? How do we communicate with people who are close by? How do we communicate with people who are far away? In this lesson, students will explore the role of communications and how satellites help people communicate with others far away and in remote areas with nothing around (i.e., no obvious telecommunications equipment). Students will learn about how engineers design satellites to benefit life on Earth. This lesson also introduces the theme of the rockets curricular unit.

Kepler's laws show the effects of gravity on orbits. They apply to any object that orbits another: planets orbiting the Sun, moons orbiting a planet, spacecraft orbiting Earth.
