Being Impulsive About Momentum Change
The Being Impulsive About Momentum Change Concept Builder is comprised of a bank of 54 questions that are delivered to the learner across three different difficulty levels. Each of the three levels has the same emphasis, but the difficulty level of the questions are noticeably different. In the first difficulty level -
Apprentice - you will be provided the initial and final momentum of an object and asked to determine the impulse or the momentum change or the force-time values that would cause such a momentum change. In the second difficulty level -
Master - you will be provided the mass and velocity of the object and asked to determine the collision parameters that would cause such a momentum change; answer options vary in type, including a mix of impulse, momentum change, and force-time values. In the third difficulty level -
Wizard - you will have to identify two different sets of collision parameters that would collectively cause the given momentum change; answer options vary in type, including a mix of impulse, momentum change, and force-time values.
The three difficulty levels in this Concept Builder are summarized as follows:
- Apprentice: Question Groups 1-6. Answer options are of the same type for each question.
- Master: Question Groups 7-12. Answer options vary in type for each question.
- Wizard: Question Groups13-18. Answer options vary in type for each question. Must pick two different collision parameters.
The questions and images used in this Concept Builder are shown below. Teachers are encouraged to view the questions in order to judge which activity is most appropriate for their classes.
