What You Will Learn
You will learn how to treat the after-effects of impact from 3 different angles of trajectory.
Why This Is Important
In this example, Newton’s law comes into play. Every action has an equal and opposite reaction, depending on trajectory into impact. Though your audience will hardly notice, the way you kick up dust, water, or in this case snow, in relation to other objects shows the physics is right. This will make your special effect supportive of the main action and as a result will seem more believable.
