Physics 1010 Final study guide correctly
solved 2026/2027
s=d/t - correct answer ✔average speed=distance traveled/time take
instantaneous speed - correct answer ✔average speed over a very small time interval (ex. average
speed in 1/10 of a second).
velocity - correct answer ✔equals speed with direction, instantaneous velocity=instantaneous speed
(ex. 15 mph north or left )
average velocity - correct answer ✔displacement divided by time taken, displacement is distance b/t
initial and final locations of the object
v=change in x/change in t - correct answer ✔average velocity=change in position/time taken
a=change in v/change in t - correct answer ✔average acceleration=change in velocity (m)/ time
taken(s)
Newtown's first law of motion (law of inertia) - correct answer ✔the velocity of an object remains
constant unless an unbalanced force acts on the object
a=Fnet/m - correct answer ✔acceleration(m/s^2)=net force(N)/mass (kg)
Newtown's second law - correct answer ✔The net force on an object is equal to its mass times its
acceleration and points in the direction of the acceleration
, mass vs weight - correct answer ✔mass=mass is not dependent on location in the universe, constant
property that depends only on how much there is of x. weight=depends on location in universe, object is
attracted to earth, depends on strength of gravitational attraction
W=mg - correct answer ✔weight (N)=mass (kg)x acceleration due to gravity (m/s^2)
terminal speed - correct answer ✔speed where air resistance equals weight, no longer net force,
acceleration stops, speed remains constant, maximum speed of object
static friction - correct answer ✔frictional force equal in size and opposite in direction to applied force
of object
kinetic friction - correct answer ✔if applied force of object exceeds max static frictional force, the
object now has acceleration and the existing friction is kinetic friction, it is less than the max value of
static frictional force, has constant value, independent of the speed of the object
Newtown's third law - correct answer ✔If an object exerts a force on a second object, the second
object exerts an equal force back on the first object
centripetal force - correct answer ✔force that acts towards the center of a circle, center-seeking force
change in v=vf-vi - correct answer ✔change in velocity=final velocity minus initial velocity
a=v^2/r - correct answer ✔centripetal acceleration=velocity squared/radius
law of universal gravitation - correct answer ✔any two objects have a force of attraction between
them, gravity exists between all objects
