In order to look at all of the energy that is going on when the bird is moving on the planet Neptune, we have to take into consideration his mass, the gravity of Neptune, along with how high he is at certain times. We also needed to know the velocity of the bird. When we know what these variables are, we can plug them into Kinetic and Potential Energy of the tiny bird in order to find out the Total Energy that the bird has. To find the height of the bird, we figured that one inch on the screen would equal two meters.
Tiny bird's mass is 2.5 kg
His velocity is 1.42 m/s
His height is 2 meters
The acceleration of gravity acting on him is 11.46 m/s^2 considering he is on Neptune
In order to know his energy we must first look at the different energies he possesses:
Due to the coefficient of friction, he has the force of friction acting upon him. He also has kinetic energy and potential energy.
We then can see that our bird at the top of the hill has 103.1 J of energy. With how the energy is distributed looking at a bar chart of total energy below:
This graph shows just how much friction there is in this game.
