This applet design by prof Hwang, modified layout by Ahmed.
Original applet Bouncing ball with rotation
The following simulation show a ball bouncing off the ground.
The ratio of velocity after bouncing to velocity before bouncing is eta.
i.e. vy'=eta *vy; (eta=0.95 as default)

The momentum change $\Delta P= m (eta+1)vy$
Assume the friction coeffieient is mu=0.1
The friction between ball and the ground produce momentum change and angular momentum change during bouncing.

• Please feel free to post your ideas about how to use the simulation for better teaching and learning.
• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
