Acceleration is measured in
m/s^2
Acceleration=
change in velocity
/
time taken
Change in velocity is measured in
m/s
Time taken is measured in
seconds
Change in velocity=
final velocity
-
initial velocity
Velocity
is the
speed
of an object in a given
direction.
What is Newton's second law?
The
acceleration
of an object is
proportional
to the
resultant
force
and
inversely
proportional to the
mass
The equation for Newton's second law is:
Force=
mass
x
acceleration
Inertial mass is a measure of how
difficult
it is to
accelerate
on an object
Uniform acceleration is when the speed is changing at the
same
rate. So it is accelerating
constantly.
Uniform acceleration:
(
final
velocity) ^2 - (
inital
velocity) ^2 = 2 x
acceleration
x
distance
v^2
-
u^2
= 2as
V represents the
final
velocity (m/s)
U represents the
inital
velocity (
m/s
)
A represents the
acceleration
(m/s^2)
S represents the
distance
(
m
)
