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

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...

Tornado in a Bottle Inquiry
Tornado in a Bottle Inquiry

Tornado in a Bottle InquiryWe will use funnels, soda bottles, and a toy called a Tornado Tube to explore the concepts of moment of inertia, rotational motion, angular momentum, kinetic and potential energy, and air pressure in an attempt to...

Horizontal Projectile
Horizontal Projectile

Students will use a simple method, employing just a meter stick and stopwatch, to determine the initial velocity of a horizontal projectile. They will then predict the range of the projectile, precisely measure the actual range by using carbon paper,...

Acceleration and Gravity
Acceleration and Gravity

When a car is on a ramp, a portion of its weight works to roll it down the ramp. Another portion works to hold it down to the ramp. These two portions, or component forces, are perpendicular to one another...

Forces in Equilibrium
Forces in Equilibrium

Students will place three different forces on a washer, and then arrange the forces so that the washer is in stable equilibrium in the center of the table. The forces must be visualized as vectors to understand how they can...

Life-Size Collisions
Life-Size Collisions

Students will observe "explosions," in which one student on a dynamics cart pushes another. From this, they will confirm the relationship between mass and velocity in determining momentum. They will also reinforce the idea of a closed system by experimenting...

Circular Motion and the Flying Pig
Circular Motion and the Flying Pig

The Flying Pig provides students with a fun way to study circular motion. The pig and its string trace a conical pendulum and allow a perfect opportunity for calculations and measurements of circular motion. Students should be familiar with forces,...

Equilibrium and Torque
Equilibrium and Torque

This lab has two activities. In the first, students investigate the arrangement of masses on a center-pivot lever required to produce balance. They will develop the idea that both force and lever arm produce torque, and that both quantities must...

Collisions on an Air Track
Collisions on an Air Track

In this lab using an Air Track, students will investigate elastic and inelastic collisions on an air track. Evaluate conservation of momentum and energy. Download Teacher Notes and Student Worksheets Required Equipment

Racing Marbles: The Race
Racing Marbles: The Race

Two marbles will roll simultaneously on different paths, starting and ending at the same height. Students will predict and then observe the results of a "race" between the two marbles, and explain the results. Quantitative analysis of the motion will...

Observing Acceleration with an Accelerometer
Observing Acceleration with an Accelerometer

Use a liquid accelerometer to observe different types of motion and classify the acceleration. Students will observe straight-line motion (constant velocity and constant acceleration), and then take their knowledge of the water's behavior to more complex circular and pendulum motion....

Acceleration Due to Gravity
Acceleration Due to Gravity

The first experiment will use very basic equipment to measure an important quantity, the acceleration of an object in freefall. This is also known as the acceleration due to gravity, or g. The acceleration due to gravity is nearly the...
