Forces and energy Flashcards
What is the equation for work done
W= F x D
The equation for power
Work done divide Time
Equation for elastic potential energy
Elastic p = 0.5 x Force x Extension
E= 0.5 x F x E
Define power
The rate of doing work
What happens to an object that gains energy
It gets faster or higher
Equation for spring constant
Force divided extension
K= F divided E
Define specific heat capacity
The measure of how hard it is to increase the temp of an object
This allows us to calculate the thermal energy
Equation
GPE= Mass x GPE x Height
Define spring constant
Is a measure of how difficult it is to stretch a spring
Define Kinetic energy
The movement energy that an object has
How is work done measured
in Newtons
Equation for thermal energy
Thermal energy = Mass x SPC x Change in temp
Q= M x C x CH in temp
Equation for kinetic energy
Kinetic = 0.5 x Mass x Velocity squared
Define gravitational potential energy
A sum of energy that a object has above the Earths surface
What is the equation for when the object is moving vertically
Mass x 10 Kg
