Mission MC3 Impulse and Momentum Change Variables

Mission MC3 focuses on the interdependence of the variables in the impulse-momentum change equation. You will have to predict the effect that variations in one variable have upon the other variables. The mission consists of 32 questions organized into 8 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...

• The student should be able to identify the effect (or non-effect) of alterations in the time and the force upon other collision variables (such as velocity change, momentum change, and impulse).
• The student should be able to identify the effect (or non-effect) of alterations in the mass and the velocity change upon other collision variables (such as force, momentum change, and impulse).

If you are not familiar with this topic, then you should first learn about the topic using our written Tutorial or our Video Tutorial:
 

• What effect would an alteration in the collision time have upon the subsequent impulse and momentum change (assuming a constant force)?
• If a impulse stops a moving object, then how would an alteration in the collision time effect the force, the impulse and the momentum change?
• If an impulse stops a moving object, then how would an alteration in the mass of the object effect the collision time, the impulse and the momentum change (assuming a constant force)?
• If a moving object is colliding with a stable surface, in what way will bouncing effect the velocity change, momentum change and impact force?
• In what way will a collision of a moving object with a hard surface be different than a collision with a soft surface?
• In what way do air bags in cars protect the passengers when a car collision occurs?
