PHYS 1010 - Exam 1 study notes verified
to pass 2026/2027
Three fundamental properties - correct answer ✔Mass
Length
Time
Mass - correct answer ✔the amount of matter or "physical substance" which an object or group of
objects possesses
Length - correct answer ✔the distance between two points in space
time - correct answer ✔the period or interval between two events
Unit of mass - correct answer ✔the kilogram
*on the earth, 1 kg has a weight of 9.8 newtons. this is approximately 2.2 lb.
Unit of length - correct answer ✔the meter
*1 m is approximately 3.28 ft
1 m = 100 cm
1 km = 1000 m
unit of time - correct answer ✔the second
*60s = 1 min etc
Speed - correct answer ✔the rate at which someone or thing is able to move or operate
, V=D/t
equation for speed - correct answer ✔V=D/t
V=speed
D=distance
t=time
velocity - correct answer ✔the speed of something in a given direction
3 ways to change velocity - correct answer ✔1- changing speed
2- changing the direction
3- changing the direction AND speed
acceleration - correct answer ✔increase in the rate or speed of something; basically how quickly
velocity changes (change in speed, acceleration, direction)
equation for acceleration - correct answer ✔a=v/t
a=acceleration
v=velocity
t=time interval
Newton's 1st law of motion - correct answer ✔an object at rest stays at rest and an object in motion
stays in motion with the same speed and in the same direction unless acted upon by an unbalanced
force
