So to wrap up the year in AP Physics 1, we have to take videos or pictures of physics in everyday life. Two of my situations are:

1. Situation where you have greatest net torque

2. Situation where acceleration changes both speed and direction at same time

For the first one, I was thinking of a seesaw, or a big wrench because if you have a big wrench since torque= force x distance the bigger distance would result in a greater torque?

For the second one, I was thinking of a swing? But had trouble explaining how the speed is changing while on a swing?

Please help if you can, and maybe give your own input!

Thank you!
