Analyzing energy

Today in class we did something very interesting. We used tracker to understand how different types of energy appear in a cart. I learned that the kinetic energy of an object affects the speed in many ways. We saw in the velocity graph that when the cart was moving down the ram it was gaining speed but when it got to the bottom it started to decrease. We also saw in the kinetic energy graph that it was the same. When the cart was moving down the ramp the energy was increasing and when it got to the bottom it started to decrease. We can conclude that the velocity comes from the gravitational energy of the cart converting into kinetic and/or mechanical as it moved down the ramp  so it gained more velocity. When the cart got to the bottom of the cart it decreased because the cart didn't have any gravitational energy to convert into kinetic so i started to lose the velocity.

  1. Great work. I like the way you referred to the graph, but in the summative, compare both of the graphs together, velocity and kinetic energy.
