a. P4.1 Energy Transfer

location to another. They also transfer energy to
objects during interactions (e.g., sunlight transfers
energy to the ground when it warms the ground; sunlight
also transfers energy from the Sun to the Earth).

Work is the amount of energy transferred during an
interaction. In mechanical systems, work is the amount
of energy transferred as an object is moved through
a distance, W = F d, where d is in the same direction
as F. The total work done on an object depends on
the net force acting on the object and the object’s
displacement.

are common in moving objects. In frictionless systems,
the decrease in gravitational potential energy is
equal to the increase in kinetic energy or vice versa.
