Photoshop animation

Here i attempted to make a ball bounce down a hill using squash and stretch. In the future i need to work out how to create a realistic, fixed backdrop, or to get multiple things interacting with each other within the animation.

my across the screen squash and stretch was my first attempt at photoshop animation using the squash and stretch technique.i feel it worked well although the ball should bounce higher in the middle bounce and i think the last squash is to much for the impact.

Here i did a ball moving across the screen to get used to the movement in photo shop as i had never done it before. I did not use squash and stretch here which makes the ball look pretty lifeless.

Pendulum one, didn't work all to well. This was my first attempt at doing arcs, and as you can see i got confused by the string of the pendulum. Also it flips over which makes little sense.. because of this i had a second go using a simpler pendulum.

Pendulum two, more effective movement using the arc rule here, also the speed feels more real with this gif then the other pendulum.
