The purpose of this experiment is to fully explain how starting height and mass affect an object’s potential and kinetic energy. Potential energy is stored energy. Potential energy related to an object’s height is called gravitational potential energy. The formula for calculating gravitational potential energy is Gravitational potential energy = Weight × Height. Kinetic energy is the energy an object has due to motion. The formula for calculating kinetic energy is Kinetic Energy = ½ × Mass × Velocity. Speed of an object is the distance the object travels per unit of time. The formula for calculating speed is Speed = Distance ÷ Time. How does the starting height of an object affect an object's kinetic and potential energy ? The independent variable is the object's height. The dependent variable is the kinetic energy and potential energy. The hypothesis is if an object's height is shorter or taller than it won't affect kinetic and potential energy because it doesn't affect energy. Is this introduction okay for a lab report?
Kinematics
A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine parts, those two parts experience a relative motion with each other. Studying such relative motions is termed kinematics.
Kinetic Energy and Work-Energy Theorem
In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the direction of displacement and perpendicular to the displacement which is called the normal force. Energy is the capacity of any object doing work. The SI unit of work is joule and energy is Joule. This principle follows the second law of Newton's law of motion where the net force causes the acceleration of an object. The force of gravity which is downward force and the normal force acting on an object which is perpendicular to the object are equal in magnitude but opposite to the direction, so while determining the net force, these two components cancel out. The net force is the horizontal component of the force and in our explanation, we consider everything as frictionless surface since friction should also be calculated while called the work-energy component of the object. The two most basics of energy classification are potential energy and kinetic energy. There are various kinds of kinetic energy like chemical, mechanical, thermal, nuclear, electrical, radiant energy, and so on. The work is done when there is a change in energy and it mainly depends on the application of force and movement of the object. Let us say how much work is needed to lift a 5kg ball 5m high. Work is mathematically represented as Force ×Displacement. So it will be 5kg times the gravitational constant on earth and the distance moved by the object. Wnet=Fnet times Displacement.
