energy
the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms
what is energy
the correct formula to calculate work
what is W = F * d
momentum ....... semi truck full of logs
what is semi-truck full of logs has a large mass and must slow down long before a stop light because even with a small velocity
momentum
what is Dividing the distance by the time to calculate the velocity or speed of the object.
energy is stored energy?
what is potential energy
the distance between the start point and the end point
what is distance
force
what is Applied Force , Gravitational Force , Normal Force , Frictional Force, Air Resistance Force , Tension Force.
force
what is force is equal to mass (m) multiplied by acceleration (a).
standard unit of measurement for energy in physics
what is joule
two measurements are needed to calculate work
what is force and distance
joule dealing with apples
what is lifting an apple
potential energy
what is P.E. = mgh,
energy is generated by the movement of electrons?
what is Electrical energy
work occurs when a _____ acts on an object to move it some distance from the start point.
what is force
type of work dealing with a car
Pushing a car horizontally from rest
kinetic energy
what is KE = 0.5 x mv2.
type of energy comes from movement or motion
what is Kinetic energy
a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force.
what is work
examples of energy
what is light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy
work
W = F * d
