Quick explanation

Understand impulse as the product of force and the duration for which the force acts; remember and apply the formula ∆ impulse = F t = ( mv )

  • This point belongs to Momentum, especially Momentum outcomes.
  • You need to be able to understand impulse as the product of force and the duration for which the force acts; remember and apply the formula ∆ impulse = F t = ( mv ).
  • The key ideas to know are Define, Recall, and Use.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Description

Understanding Impulse

Impulse is defined as the product of force and the time duration for which the force acts. It is crucial in understanding changes in momentum during collisions.

  1. a

    State the formula for impulse.

    Aim for approximately 1 distinct marking point.
