Question 1
______ is done when force applied to an object moves the object:
A. Transformation
B. Biological Kindness
C. Conservation
D. Work
Answer: D. Work
Rationale: In physics, work is defined as the transfer of energy that
occurs when a force is applied to an object and causes it to move in the
direction of the force. The formula for work is W = F × d (Work = Force ×
distance). Transformation (A) refers to changing energy forms, not the
definition of work. Biological Kindness (B) is not a scientific term related
, to physics. Conservation (C) refers to the principle that energy cannot
be created or destroyed, not the definition of work.
Question 2
A windmill is used to create electrical energy. This change from one
form of energy to another is called:
A. Energy transformation
B. Kinetic energy
C. Mechanical energy
D. Electrical energy
Answer: A. Energy transformation
Rationale: Energy transformation is the process of changing energy
from one form to another. In a windmill, the kinetic energy of moving
air (wind) is converted into mechanical energy (rotating blades), which
is then transformed into electrical energy by a generator. Kinetic energy
(B) is the energy of motion, not the process of change. Mechanical
energy (C) is a form of energy, not the process of conversion. Electrical
energy (D) is also a form of energy, not the process of change.
