PHYS 1010 Final Exam Questions And
Answers 2025
/. the study of motion, matter, energy and forces. This basically means figuring out how
things in our world work. - Answer-Physics
/.Questions which we would now consider to be physics questions originally fell within
the field of ________________. - Answer-philosophy
/.The Greek philosopher __________________(384 -322 B.C.) attempted to describe
the motion of objects. His theory was the predecessor to modern physics, but was not
really "physics" in the way we now think of it. - Answer-Aristotle
/.Aristotle suggested that the world was composed of four elements in the order of?
(from bottom to top) - Answer-earth, water, air, fire
/.The natural state of objects was to be at rest in their proper order, and objects would
naturally move to achieve this natural state. Who said this? - Answer-Aristotle
/.What were the major weaknesses of Aristotelian physics? - Answer-neglected friction
and air resistance
/.________________ published his theory that the Sun rather than the Earth was in the
center of the universe in his book entitled On the Revolution of the Heavenly Spheres -
Answer-copernicus
/.Who is often referred to as the Father of Modern Science and why? - Answer-Galileo
because when he did not believe aristotelian physics to be correct, he conducted
experiments and gathered data to find the truth, for this approach to answering
questions, he is known by this name.
/.What experiment was used by Galileo to disprove Aristotle's ideas on an objects
"natural motion"? - Answer-balls rolled uphill and downhill on different inclines
/.For the speed of an object to change, a ___________ must act upon it - Answer-force
/.What did Galileo conclude considering the natural motion of objects? - Answer-Objects
will continue moving at a constant speed unless somethings acts to cause a change in
the speed
/.The property of an object to resist a change in its motion - Answer-inertia
/.how quickly its position is changing with time. - Answer-speed
, /.when an object is moving at a constant speed, the distance versus time graph is a
straight line, and the speed of the object (cart in this case) is described by the slope of
the graph. Moving faster causes a _____________ slope, and moving slower causes a
shallower (less steep) slope. - Answer-steeper
/.What is the formula for speed? - Answer-speed=distance/time
/.So if a car is traveling down the highway at a constant speed from Ogden to Salt Lake
City, which is approximately 45 km away, and if it takes 45 minutes = 0.75 hours for the
trip, then the speed of the car is? - Answer-60 km/h (speed=45 km/0.75 h)
/.when an object's speed is changing we say that it is _________________. - Answer-
accelerating
/.your speed AND the direction you are going together. - Answer-velocity
/.a change in velocity. - Answer-acceleration
/.Every object continues in its state of rest, or of uniform motion in a straight line, unless
it is compelled to change that state by forces impressed upon it - Answer-Newton's 1st
law
/.All objects on the Earth are moving at ________ km/s as the Earth revolves around
the Sun. - Answer-30
/.greater forces cause greater ___________________. - Answer-accelerations
/.less _________ results in more acceleration - Answer-mass
/.What is the equation for Newton's 2nd law of motion? - Answer-a=F/m or a*m=F
/.If a 5 kg mass has an acceleration of 2 m/s2, what is the force acting on it? - Answer-
10 N (a*m=F, so 5*2=10 N)
/.Two forces: 20 N to the right, 25 N to the right
Net force:? - Answer-45 N to the right
/.If you have no force at all, then Newton's second law says that your acceleration will
be ________, which is the same as saying that your velocity does not change. -
Answer-zero
/.a measure of an object's inertia. - Answer-mass
/.___________ is a property of an object which never changes. So a person which has
a mass of 50 kg on the Earth, will have a mass of 50 kg on the Moon, and a mass of 50
