Question

e) The impulse delivered to an object by a force is (circle all correct answers)

(show work that supports answer)

i) defined only for interactions of short duration.

ii) equal to the change in momentum of the object.

iii) equal to the area under an F versus x graph.

iv) defined only for elastic collisions.

v) defined only for inelastic collisions.

Answer 1

option (I) is incorrect because impulse is defined for all lengths of time and not only for short duration.

Option (III) is incorrect because area under F X graoh gives work done and not the impulse delivered.

Option (IV) and (v) are incorrect because impulse is valid for both elastic as well as inelastic collision.
