Product Description

A **4-page lab activity** that challenges students to investigate **Newton’s second law of motion** by **determining the relationship between mass, net force, and acceleration of an object**.

In this activity, students are provided a Ping-Pong ball, a glass marble or ball bearing (equivalent in size to the Ping-Pong ball) and a rigid wooden ruler. Students are to pull back the ruler to hit the ball or marble/bearing while observing the acceleration of the object qualitatively. This is the basic procedure, which is then modified by the students to perform the rest of the activity.

Then, in a series of**3 mini-investigations**, students are asked to change either **(1) the mass of the object** (by alternating between the Ping-Pong ball and glass marble/bearing); or **(2) the size of the net force** (by pulling the ruler back further before striking the objects) to determine the relationship between mass, net force, and acceleration.

This lab activity arose because I wanted to a simple lab that investigated the relationship between mass-acceleration and force-acceleration without having to use complicated force sensors or perform in-depth calculations. This engaging activity, with only 3 materials to provide, is both**easy to prepare and to perform**. This **student-directed activity** typically takes pupils **half a class period to complete**. This gives educators time to review the lab with their students, relating it back to Newton’s second law of motion and the equation Fnet = ma, which is simply a mathematical representation of the relationship students discover on their own.

**Investigations That Students are to Perform:**

- Keeping the net force (Fnet) the same while changing the mass of an object

- Keeping the mass the same while changing the net force (Fnet) on an object

- Changing the net force (Fnet) in order to give 2 differently-massed objects the same acceleration

**Lab Techniques Addressed by This Activity:**

- Following a procedure

- Changing the independent variable

- Determining acceleration of an object (qualitatively)

- Analyzing data
