Acceleration Force and Mass
Acceleration Force and Mass

Students love fast moving experiments, but higher speeds often require higher technology. That can challenge the budget and students’ ability to use the technology. These simple, but highly accurate photogates remove both barriers. No costly computers are needed, and set...

Lab #6.3b Mechanics: Chapter 6  the Weight
Lab #6.3b Mechanics: Chapter 6 the Weight

Purpose In this activity, you will investigate the relationship between weight and mass. Discussion Mass and weight are different quantities. Mass is a measure of an object's inertia, the extent to which an object resists changes to its state of...

Lab #6.3a Mechanics: Chapter 6  Putting the Force Before the Cart
Lab #6.3a Mechanics: Chapter 6 Putting the Force Before the Cart

Purpose In this activity, you will observe the motion of a variety of objects under a variety of conditions. You will interpret your observations to learn the relationship between force, mass, and acceleration. Discussion Some of the most fundamental laws...

Factors Affecting Frequency
Factors Affecting Frequency

Two experiments. Choose one. In the first, students are guided through the process of testing 3 variables; mass, length, and amplitude; to determine which affects the frequency of a simple pendulum. In the second, students use inquiry and experimental design...
