JUEGO “ELEFANTE Y PLUMA” Tema Dinámica (1º Bach)

24 02 2015

Te propongo el siguiente juego: Observa el gif animado y contesta verdadero o falso a las frases que aparecen en inglés debajo de la imagen.

elefante-pluma

.

TRUE or FALSE:

  1. The elephant encounters a smaller force of air resistance than the feather and therefore falls faster.
  2. The elephant has a greater acceleration of gravity than the feather and therefore falls faster.
  3. Both elephant and feather have the same force of gravity, yet the acceleration of gravity is greatest for the elephant.
  4. Both elephant and feather have the same force of gravity, yet the feather experiences a greater air resistance.
  5. Each object experiences the same amount of air resistance, yet the elephant experiences the greatest force of gravity.
  6. Each object experiences the same amount of air resistance, yet the feather experiences the greatest force of gravity.
  7. The feather weighs more than the elephant, and therefore will not accelerate as rapidly as the elephant.
  8. Both elephant and feather weigh the same amount, yet the greater mass of the feather leads to a smaller acceleration.
  9. The elephant experiences less air resistance and than the feather and thus reaches a larger terminal velocity.
  10. The feather experiences more air resistance than the elephant and thus reaches a smaller terminal velocity.
  11. The elephant and the feather encounter the same amount of air resistance, yet the elephant has a greater terminal velocity.

Otro ejercicio de verdadero o falso:

TRUE or FALSE:

  1. The elephant and the feather each have the same force of gravity.
  2. The elephant has more mass, yet both elephant and feather experience the same force of gravity.
  3. The elephant experiences a greater force of gravity, yet both the elephant and the feather have the same mass.
  4. On earth, all objects (whether an elephant or a feather) have the same force of gravity.
  5. The elephant weighs more than the feather, yet they each have the same mass.
  6. The elephant clearly has more mass than the feather, yet they each weigh the same.
  7. The elephant clearly has more mass than the feather, yet the amount of gravity (force) is the same for each.
  8. The elephant has the greatest acceleration, yet the amount of gravity is the same for each.
