In radiologic sciences, x-rays have a constant velocity equal to
the speed of light , or—Ans: 3x10^8 m/s
what is force ?—Ans: is a push, a pull, or other action that
changes the motion of an object.
What is the unit of measure for force ?—Ans: newton (N)
what is the formula for force ?—Ans: F=ma (mass of an object
times acceleration)
What is momentum ?—Ans: is equal to the mass of the object
multiplied by its velocity
What is the formula for momentum ?—Ans: p=mv
what is work ?—Ans: is an expression of the force applied to an
object multiplied by the distance across which it is applied.

What is Power ?—Ans: is equal to work divided by time during
which work is done.
what is the formula for power ?—Ans: P=work/t
what is the unit of measure for power ?—Ans: watts(w)
What is inertia ?—Ans: is the property of an object with mass that
resists a change in its state of motion.
Newtons first law of motion states that—Ans: an object at rest will
stay at rest unless acted on by an external force.
What is energy ?—Ans: is simply the ability to do work.
What is potential energy ?—Ans: is energy in a stored state. It has

Guru01 - Stuvia
thermal.
what is electrical energy ?—Ans: is a form that is created by the
flow of electricity.
What is chemical energy ?—Ans: is a form that exists through
chemical reactions.
