## Pixar in a Box

### Course: Pixar in a Box>Unit 7

Lesson 2: The physics of particle systems

# Animating particles

Now we'll pull everything together and explore how we calculate the position of a particle over time, frame by frame. To animate particles, we calculate positions and velocities over time, using equations of motion to compute acceleration. Then, we apply these concepts to create a ping pong ball simulator!

• This is just too much info to take in one lesson. SLOW DOWN!
• I feel ya buddy :(
• This makes no sense, can someone dumb it down for me?
• OMG YEEESSSSS I am in seventh grade i am crying it so hard jesus help

• I'm interested in learning more about particle systems but I haven't studied physics in detail. Under what subcategory would this come under here on khan academy?
• I don't understand all this. I am just watching the videos because I want to.
• LOL it's really hard for me to understand, too!
Pls give us a "physics for complete dunderheads" book!!
Or at least make it a little dumber so we can understand!
• I'm interested in learning particles more because i am still struggling with the formations.
• Wait, so at the end he says that we will make our particle simulations, but where? Because I don't see any place to go and do that on Khan Academy?
• can anyone understand anything?
• i get it but i am in 4rth grade

• I have NO CLUE what any of this means!
• me either

• I could not understand the formula , if I could get some help it would be nice
• At , how did the teacher arrive upon 'p2=(t2-t1)V1+p1?' Could you show me how he got it? Also, what is the Velocity formula?
