Purpose
The purpose of the experiment is to quantitatively compare magnitude of the momentum of a
moving cart with the impulse of its inelastic collision with a stationary object.

• RMS/IDS Kit (CI-6569) • Force Sensor Bracket & Collision Bumpers (CI-6545)
• IDS Mount Accessory (CI-6692) • PASCO computer interface (500 or 700)
• Dynamics Cart (ME-9430 or ME-9454) • Science Workshop version 2.2 or higher
• Dynamics Track (ME-9435A or ME-9458) • computer
• pages 2 & 3 of this manual • block of wood (or similar) about 10 cm in height
Experiment 2: Comparison of momentum and impulse of an
inelastic collision
Theory
The momentum of a system is determined by the relationship:
where P = momentum, m = mass, and v = velocity.
The impulse, or change in momentum, of a collision is determined by the relationship:
The area under the curve of a graph of the force versus time, as determined by integrating the
curve, equals the total change in momentum.
In an inelastic collision, where the final velocity is zero, the following relationship exists:
Procedure
Set Up the Equipment
1. Mount the RMS on the IDS track using the IDS Mount Accessory, and mount the IDS track
pulley bracket on the IDS track (refer to the equipment setup section, pages 2 & 3, of this
manual).
