Energy
The sum of the potential and kinetic energies in a system.
What is the definition of mechanical energy?
mgh = ½ mv^2
What is the conservation of energy formula?
A waiter carrying a tray.
What is a basic example of no work being done?
The rate in which work is done.
What is the definition of power?
Energy transforms from kinetic to potential energy
How does energy transform on a roller coaster?
GPE=MGH
What is the gravitational potential energy equation?
Energy can neither be created nor destroyed; rather, it transforms from one form to another.
What is the law of conservation of energy?
W = Fd = mgh
What is work done against gravity?
Watts
What is the SI Unit for power?
Isaac Newton
Who is recognized as the father of physics?
The energy stored in an object as the result of its vertical position or height.
What is gravitational potential energy?
The total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.
What does the principle of the conservation of mechanical energy state?
The magnitude of the force multiplied by the distance moved by the object in the direction of the applied force.
What is work?
Power=energy/time
What is the formula for power?
Kinetic, potential, and gravitational potential.
What are the different types of energy?
The ability to do work
What is the definition of energy?
Te total amount of mechanical energy is the same at every location along the track.
What does conservation of energy on a roller coaster mean?
W = Fd = mad = ½ m(vf)² – ½ (mvi)²
What is the equation for work done on accelerating an object from initial to final velocity?
When work is done faster or energy is transferred in less time.
When is power increased?
Thomas Young
Who invented the term energy?
KE=(1/2 mv^2 )
What is the kinetic energy formula?
The amount of kinetic energy and the amount of potential energy is constantly changing. Yet the sum of the kinetic and potential energies is everywhere the same.
How does potential energy and kinetic energy work on a roller coaster?
W = Fd = ½ kx²
What is the equation for work done on a spring (compression or stretch)?
James Watts and James Prescott Joule
Who were two notable people of power in physics?
1 Joule = 1 kg • m2/s2
What is the equation for a joule?
