the ability to do work and change matter
energy
the SI unit of work and energy
joule
energy of motion
kinetic energy
associated with the position of an object and the forces acting upon it
potential energy
energy from motion or forces that affect the entire object
mechanical energy
states that energy can neither be created nor destroyed, only transferred
law of conservation of energy
states that mass and energy can be considered 2 different ways of measuring the same physical property
mass-energy equivalence
states that the sum of mass and energy is constant
law of conservation of mass and energy
energy of an entire object moving
whole-body kinetic energy
whole-body kinetic energy caused by translational motion
translational kinetic energy
an object changing in location/space
translational motion
motion in which an object spins or rolls around an internal axis
rotational motion
kinetic energy caused by rotational motion
rotational kinetic energy
4 factors affecting rotational kinetic energy
mass, speed, size, shape
internal energy that an object has because of the random motions of its individual molecules
thermal energy
energy caused by a disturbance moving through a substance
wave energy
the energy associated with the position of an object and the forces acting upon it
potential energy
any of the 4 natural forces that cause potential energy
fundamental force
the attractive force between all objects
gravitational force
model that represents the direction and strength of a body’s gravity at every point in space
gravitational field
potential energy that an object gains from the work used to move it against a gravitational field
gravitational potential energy
the 4 types of fundamental forces
affects certain subatomic particles; stronger than the gravitational force but weaker than the electromagnetic force
weak nuclear force
second-strongest fundamental force, which only affects objects with an electric charge; includes electricity and magnetism
electromagnetic force
