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...

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...

Force and Inclined Plane
Force and Inclined Plane

Students will elevate the car in two ways: lifting directly and pulling up the ramp. They will find that it takes less force to pull the car up the ramp, but they do more work. The extra energy goes into...
