Law of Physics 5.2

1.  Describe how the Laws of Physics affect animation.  

Before creating eye-opening animations, you need to be able to understand the basic laws of physics. The laws determine how objects look and move in real life, by doing this you can make your animations look more realistic. 

2.  List the 8 laws of physics mentioned in the chapter.  For each one, describe a scenario/animation that might illustrate it. (for example: Damping Force - a basketball only bounces twice in a field of grass).  Try to be creative and create a scene that is not already offered in the book. 

Mass- If your two objects are a tree leaf and a bowling ball, the bowling ball will have a much greater mass as compared to a thin lightweight leaf.

Gravity-  If you drop a leaf from shoulder height, it will float down, the bowling ball will fall straight down without floating.

Weight- The weight of the bowling ball is determined by the balls mass.

Directional Force- If you was to apply a force other than gravity, for example a very very high powered air cannon shooting high psi amounts of air, you can change the direction the ball falls in. 

Arc- The amount of strength and force the ball is thrown at will affect the arc, if rock is thrown high into the air and the arc will be steeper and will and will fall sooner, thrown lower and less steeply the arc will be longer and not so aggressive.

Damping Force- For example, if you are dropping a tennis ball onto concrete or clay the ball will bounce up again much higher and will continue to bounce until the ball loses energy, where as if bounced on a carpet the ball may bounce 2 times at a very low rebound height and then stop.

Acceleration and Declaration-  If a bowling ball is thrown straight up, the ball will travel slower being thrown up than falling. This is due to the resistance of gravity when the ball is thrown up and assistance from gravity on the way down.

Resistance- If a leaf is laying on the ground and you come with a leaf blower, the leaf will be blown away, whereas a leaf blowers force would have to be much greater to move a bowling ball because of its resistance and mass.
