Even if you do only one a day, or one a week, they will provide extra practice with programming in Python, and also extra practice in doing physics. I'd also encourage you to try out the ideas laid out in the advanced material section. the bouncingball model, first presented on page 57 in Chapter 2. It's always important to test your program versus known physics this is how we know we did the programming correctly! Does the ball ever come to rest, and if so, what total vertical distance will it have traveled This. The second case shows that equations in clocked whenclauses are just normal equations. Your program may not crash but the output may not make sense physically. This is a key thing to remember when coding up solutions to physics problems. The ball just gets deflected normally.But, when either direction is hit, the case is different. When you consider the center portion: You need not differ the bounce effect of that which is applied when hitting the ball. 3.) The ball hitting the rightward position of the paddle. The idea is to use the definitions of position, velocity, and acceleration that involve a small time interval, \(\Delta t\).įor our freely-falling ball, \( a = - 9.8 \, \text\)).Īdditionally, we validated our program by relying on simple physical principles such as energy conservation. The ball hitting the leftward portion of the paddle. Before we start coding, let’s get familiar with how we can solve for the position and velocity of our ball as a function of time.
