Collisions

Choose the body or interacting system, the positive direction and the collision interval before writing a momentum equation.

Connect a force-time pulse to momentum change and select the conditions needed to predict a collision outcome.

Impulse, momentum conservation with negligible external impulse, one-dimensional two-body collisions, relative speeds and kinetic-energy changes. For 8867 (2027).

Choose a topic

  1. Impulse and a change of momentum

    Interpret signed force-time area, a rebound and the effect of contact time on average force.

  2. Choose a system for momentum conservation

    Assess external impulse, calculate a sticking collision and compare sensor and cart measurements.

  3. Elastic and inelastic outcomes

    Use the elastic relative-speed condition and compare kinetic-energy changes for the same initial carts.
