Impulse and Change in Velocity

Students collide a cart into a spring bumper attached to a force sensor, while simultaneously measuring the velocity of the cart before, during, and after the collision using a motion sensor. Using their force sensor and motion sensor data, students find Students graph impulse versus change in velocity and find that the slope of that graph is equal to the mass of the cart. Students also discover the impulse momentum equation, and use the equation to answer a series of questions.

Featured Equipment

Motion Sensor

Wireless Motion Sensor

The Wireless Motion Sensor uses ultrasound to measure the position, velocity, and acceleration of objects.

Force Acceleration Sensor

Wireless Force Acceleration Sensor

The Wireless Force Acceleration Sensor simultaneously measures force, acceleration, and rotational velocity without the inconvenience of wires.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
