Measuring force based on understanding of motion

  • Can we estimate the force the lizard exerts in the jump shown on this video?
  • According to Newton's laws a body only accelerates when it is acted upon by an unbalanced force.
    • Look at this motion graph - can we estimate the maximum acceleration of the lizard?
    • What additional information is required to calculate the force exerted by the lizard?
      • The mass of the lizard is approximately 4 grams or 0.004 kg.  Do we now have enough information?
