If I double the mass of my object moving at the same velocity, this happens to the kinetic energy
What is double it?
The kinetic energy from 1 kg moving at 1 m/s
What is 100J?
What is 0J?
The letter to represent potential energy
What is U?
The unit of mass in the potential energy equation: U = mgh
What is kg?
A massless object 10 meters above the ground has this amount of potential energy
What is 0J?
The kinetic energy from 10 grams moving at 1 m/s
What is .01 J?
The potential energy of a 100 gram paper at an elevation of 10 m
What is 1 J?
The letter to represent kinetic energy
What is K?
The units of g in the potential energy equation U = mgh
m/s^2
Work done on an object on level ground will do this
What is increase the kinetic energy?
The kinetic energy of 150 grams moving at 20 m/s
What is 60 J?
The height of a 150 kg object with -1000 J of potential energy
What is -.67 m?
This says that energy cannot be created or destroyed, only transferred
What is the Law of Conservation of Energy?
U = kx^2 is the equation for this
What is spring potential energy?
Mechanical energy not conserved goes here
What is increase in thermal energy
The mass of an object with 10 J of energy moving at 10 m/s
What is .1 kg?
The acceleration due to gravity on a planet where a 15 kg object has 150 J of energy by being elevated to a height of 100 m
What is 0.1 m/s^2?
When energy is put into a system from the surroundings
What is work?
This is the solved equation for velocity from the kinetic energy equation
sqrt(2k/m)
Potential energy comes from here
What is work done on an object?
The velocity of a 2000 kg car moving with 125 J of energy
What is .25 m/s?
The potential energy of compressing a spring a distance of 10 mm with a spring coefficient of 1500 N/m.
What is .15 J?
This is the sum of kinetic energy, potential energy and work
What is mechanical energy?
This is 1J written in base units
What is kg*m^2/s^2
