Physics: Work
What is work? - correct answer ✔the product of the force along the direction
of displacement and the magnitude of the displacement


Can work be stationary? - correct answer ✔NO


What is the SI unit of work? - correct answer ✔joules (J)


Is work a scalar? - correct answer ✔YES (magnitude only)


no force= no ________ - correct answer ✔movement


force and displacement are parallel - correct answer ✔W= F*d


force and displacement are antiparallel - correct answer ✔W= -F*d


force and displacement are at an angle - correct answer ✔W= F*d*cos O


force and displacement are perpendicular - correct answer ✔W= 0


What is kinetic energy? - correct answer ✔the energy of an object that is due
to the object's motion


What is an object's kinetic energy is it is not moving? - correct answer ✔0

, What is the KE formula? - correct answer ✔KE= 1/2*m*v^2


mass is ________ ___________ to KE - correct answer ✔directly
proportional


if mass is doubled, KE is _________ - correct answer ✔doubled


if velocity is doubled, KE is ____________ - correct answer ✔quadrupled


Can KE be negative? - correct answer ✔NO


Can gravitational potential energy be negative? - correct answer ✔YES


What is the Work Kinetic Energy Theorem? - correct answer ✔the net
(regular net force) work done by all forces acting on an object is equal to the
change in the object's kinetic energy


What is the net work formula? - correct answer ✔Wnet= change in KE


What is potential energy? - correct answer ✔the energy associated with an
object because of the position, shape, or condition of the object


What is gravitational potential energy? - correct answer ✔the potential
energy stored in the gravitational fields of interacting bodies


Gravitational potential energy must be measured relative to _______ - correct
answer ✔some zero (we pick it)
