PHYS 1010 final exam Questions with
Complete Solutions
Free fall - how far? distance = (1/2) acceleration X time X time
terminal speed when an object has reached its terminal speed, acceleration has been
terminated.
how does fluid friction vary with speed? fluid friction increases with speed
Mass the amount of matter in an object (protons, neutrons and electrons). inertia is a way
of measuring mass
weight the force of gravity
force causes acceleration acceleration is directly related to the net force. the cause is the
force and the effect is the acceleration. acceleration is inversely proportional to mass.
, newtons second law of motion The acceleration of an object depends on the mass of the
object and the amount of force applied. acceleration = net force / mass. a = fnet / m
non-free fall when an object falls downward through the air, it experiences: the force of
gravity pulling it downward, air drag force "R" pulling it upward. when the object moves fast
enough, air resistance = force of gravity.
Practice problem: a person jumping off a cliff as air resistance increases, the net force
would decrease. the acceleration has become zero and has been terminated when you reach a
certain distance/speed.
Newtons third law to every action, there is an equal and opposite reaction
Proportional reasoning use letters to represent the shadow, distance, pillar and radius. can
be expressed by showing how one thing is related to another by saying "a is to b" and "c is to d"
uncertainty in measuring creates uncertainty in our final measurement
Steps of the Scientific Method 1. choose a question
2. form a hypothesis
