How Does The Height Of A Ramp Affect The Distance Of A Toy Car
I will carry out an experiment to answer this question.I will do this by making a ramp with an adjustable height and rolling a toy car down it to see how long it travels before it stops. I will then work out the work done by using this equation -Force (n) x distance (m) = work done (mgh)I predict that the greater the slope of the ramp the longer the model will take to stop.This will happen because the higher…...

Heat Engine Lab Report
Heat engine lab Intro: when an engine runs, it pumps pistons that move up and down and provide energy to the engine to it to go. These pistons move because of pressure and heat. This work done on the system is not only mechanical but its also thermodynamic. When a piston undergoes one full cycle its displacement is zero because it comes back to its resting place. This means that its net thermodynamic work to be done should also be…...

Egg Drop Experiment Lab Report
Things we learned that was relevant to the lab were what Potential Energy and Kinetic Energy was. Potential Energy is stored energy due to objects relative position, while Kinetic energy was energy of motion; amount of energy depends on objects mass and velocity. The lab with the roller coaster showed examples of when the coaster was at the highest point that it had more Gravitational Potential energy and that by the time it reached the bottom or the lowest point…...

Simple Harmonic Motion Lab Report
Motion Lab Report Introduction Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooker’s Law. In this lab, we will observe simple harmonic motion by studying masses on springs. In the first part of this lab, you will determine the period, T, of the spring by observing one sliding mass that is attached to two springs with the spring constant k, and attached to a…...

Wheel And Axle Lab Report
Now for a rolling wheel the kinetic energy has two monuments, translational due to the bodily movement of the mass centre down the slope and rotational due to the wheel spin. Now the source of this energy is the loss in potential energy as the wheel moves down the slope. If it is reasonable to assume that friction effects are insignificant then no energy is lost. Thus the loss in potential energy becomes a gain in kinetic energy.Essay Example on…...

Energy: Vital for Global Development
Energy is a key requirement needed for the world to develop. Most countries in the world see energy as the most important factor needed for agricultural and industrial development (Muralikrishna and Lakshminarayana 50). As the world population grows, the demand for energy is increasingly becoming a problem. The issue of climate change along with the steady decrease of the world’s fossil energy reserves has worsened the global energy crisis. Conservation of energy, therefore involves both the careful use of currently…...
