Introduction
When we watch movies, we usually are caught up in the moment or action of
the scenes that we tend to not notice things that may or may not be able to
happen.
A.
Action and Reaction
1.
For every action force, there is an equal
reaction force in the opposite direction.
B.
Movies that break this law:
1.
Iron Man at (1:45:47)
2.
Transformers (1:50:40)
3.
The Incredibles (00:37:40-00:00:38:00)
Body
A.
Iron Man 2008
1.
Near the end at 1:45:47, Iron man was able to
catch a car with a family inside that was about 10-15ft in the air because the
villain drops it. He caught the car when he was on ground with little reaction
or recoil from the weight of the car. Even when his suit was around 17%
capacity.
2.
What is wrong with the scene is that a car
weighs about a ton or two, add a few hundred pounds with the people inside. The
car does not fall at terminal velocity of course because it falls a short
distance, but the weight of it and Iron Man catching the car should have had a
bigger reaction. The timing seems fine, bit the recoil or overshoot was stiff.
The reaction is the force it took to catch the car. Gravity of car pushes down,
iron man does not have enough recoil to show his resistance/ force upon the
car.
B.
Transformers 2007
1.
Around or start of 1:50:40, the scorpion type robot’s
jumps while rollerblading towards Optimus Prime on the highway. The force of
the jump and tackle has them falling off the bridge highway ramp.
2.
The opponent scorpion robot’s takeoff of the
jump did not seem to have enough force to take down Optimus. It did not bend
its knees enough to generate enough force. The machine was also on wheels so I
do not know if that reduces the friction of moving forward on wheels and the
ground.
3.
Also when they fall down to the lower level of
the ramps, the impact should have caved in the roadway since they would both
seem to weigh more than an average car and that there are two of them.
C.
The Incredibles 2003
1.
Mr. Incredible hits the giant robot maybe about
30ft or so and robot hits tree, but tree does not break from impact.
2.
Robot this time smacks/ hits Mr. Incredible into
(what appears to be) a bigger tree yet the tree breaks from impact.
3.
Breaks action and reaction because of weight of
the bigger object’s force did not react the breaking of its tree. Tree should
have broke from the impact of the force. The air time of the robot may have
been slow but the mass of the object should have at least knocked the tree down
if not break it than Mr. Incredible breaking his tree on impact.
Conclusion:
CG or
animation, sometimes rules have to be broken to make characters seem believable.
