Kinetic Energy Flashcards
What is Kinetic Energy?
The Energy an object or body possess due to its constant motion.
What key factors determine how much Kinetic Energy an Object has, and why?
Speed and Mass.
The more speed an object is travelling at = the more Kinetic Energy it has.
The more massive an object is = the more kinetic energy it has when in motion.
What is the Equation to calculate the Kinetic Energy and object possess?
Ek = 0.5 MV(^2)
E = Energy, K = Kinetic, M = Mass, V(^2) = Velocity Squared.
Energy Possession is measured in Joules.
Therefore Kinetic Energy is equal to One Half of the Mass of the object Multiplied by its Velocity squared.
How do you do the equation correctly?
All numerical values need to be in their correct units.
E.G > KG is the unit of mass so a 20tonne body must be converted into 20,000kg before the equation is done.
How do you solve for the mass of a moving object when given its kinetic energy?
M (mass in kg) = Ek /0.5 x V(^2)
Mass is equal to kinetic energy divided by 0.5 multiplied by the velocity squared
