Jessica Alba's weight is 540 newtons. According to the Third Law, if the Earth pulls on Jessica Alba with a force of 540 N, then Jessica pulls on the Earth with a force of 540 newtons that acts in the opposite direction. However, if Jessica Alba stumbles while rollerblading, she will fall down to the ground. Explain why this happens.

well i think the question is asking, why doesn't earth 'fall into' or move towards jessica alba
perl
  • perl
if jessica falls towards earth when she is not supported by her rollerblades on the ground, why doesn't earth fall towards jessica? doesn't newtons third law say force comes in reaction pairs
perl
  • perl
the answer is, yes the earth does accelerate towards jessica, but because of earth's giant mass, the acceleration is not noticeable, its insignificant

oh ok
perl
  • perl
force = mass * acceleration 540 newtons = earth mass * acceleration if you divide 540 by earth mass, acceleration will be tiny

  • yadu123
makes total sense now
perl
  • perl
but with jessica 540 newtons = jessica's mass * acceleration dividing 540 by her mass (which is about 54 kg) , that causes 9.8 or about 10 m/s^2 acceleration
