What are 2 things required for work to be performed?
In order for work to be done on an object, what must happen to the object? A force must be applied to the object and the object must move at least partly in the direction in which the force is applied.
What is the formula for calculating work?
The formula for work is , work equals force times distance. In this case, there is only one force acting upon the object: the force due to gravity.
What is Ke formula?
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
What is PE and Ke?
Summary. Energy is the ability to do work. Potential Energy (PE) is stored energy due to position or state. PE due to gravity = m g h. Kinetic Energy (KE) is energy of motion.
What is the type of relationship KE and PE have?
We know that potential energy is the energy that is stored within an object while kinetic energy is the energy that is in motion. The connection between the two is that potential energy transforms into kinetic energy.
How do you find Ke?
In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
What is the negative work?
In the context of classical mechanics as you describe, negative work is performed by a force on an object roughly whenever the motion of the object is in the opposite direction as the force. Such a negative work indicates that the force is tending to slow the object down i.e. decrease its kinetic energy.

Is the force evil?
The Force, like nature itself, is neither inherently evil nor inherently good. To the Jedi, the Force is good – so there is no reason to differentiate or even mention “the Light side of the force” because to them it’s just the Force or the Force corrupted and used for evil, the Dark Side.
Is KYLO Ren a Sith?
A dark side warrior with a mysterious past, Kylo Ren was neither Jedi nor Sith, but a product of both sides’ teachings. Once an apprentice of Luke Skywalker’s, he killed his fellow students and drove Skywalker into exile, becoming a First Order warlord and servant of Supreme Leader Snoke.
