Resumen del Recurso

Pregunta 1

Pregunta
Momentum is measured in kg m/s or [blank_start]N s[blank_end].
Respuesta
  • N s

Pregunta 2

Pregunta
momentum = [blank_start]mass[blank_end] x [blank_start]velocity[blank_end]
Respuesta
  • mass
  • velocity

Pregunta 3

Pregunta
The principle of conservation of momentum states: When [blank_start]two[blank_end] or more [blank_start]bodies[blank_end] act on one [blank_start]another[blank_end], as in a collision, the total [blank_start]momentum[blank_end] of the bodies remain [blank_start]constant[blank_end], provided no [blank_start]external[blank_end] forces act (e.g. friction).
Respuesta
  • two
  • bodies
  • another
  • momentum
  • constant
  • external

Pregunta 4

Pregunta
Momentum is a vector quantity.
Respuesta
  • True
  • False

Pregunta 5

Pregunta
Momentum is conserved in an explosion.
Respuesta
  • True
  • False

Pregunta 6

Pregunta
force = [blank_start]change of momentum[blank_end]/[blank_start]time[blank_end]
Respuesta
  • change of momentum
  • time

Pregunta 7

Pregunta
impulse = [blank_start]force[blank_end] x [blank_start]time[blank_end]
Respuesta
  • force
  • time
