Speed
1.
Speed is defined as the …………………… travelled in a certain
interval of time or the …………………............
of distance traveled with time.
Speed
= Distance traveled
Time taken
2.
The speed of an object is a ……………………… quantity. The SI units for speed is …………………..
Velocity
1.
Velocity is defined as the …………………….. travelled in a
given interval of time in a ………………………………….. or the rate of change of …………………….. traveled with time.
Velocity = Displacement
Time take
2.
The velocity of an object is a …………………….. quantity. The SI units for speed is
………………..
Acceleration
1.
Acceleration is defined as the rate of change of velocity.
Acceleration
= Change of velocity
Time taken
a = v  u
t
v  the final velocity
u – the initial velocity
t – the time taken
1. The ticker timer as
shown in figure is used in the laboratory
to study motion.
2. It can print dots on a
tape at a steady rate.
3. It is connected to an
a.c . power supply of 50 Hz.
4. The time taken to make
50 dots on the ticker tape is 1 s. Hence , the time interval between 2
consecutive dots ( 1 tick) is 1/50 = 0.02 s.
Calculation
involved ticker tape :
What is the
speed of the trolley ?
The tickertape charts constructed
with 5tick lengths is shown in the Figure
above. What is the velocity of the trolley if the tickertimer was
connected to a 50 Hz power supply?
I simply want to say I am new to weblog and truly savored you’re website. More than likely I’m want to bookmark your blog . You actually have excellent writings. Thanks a bunch for sharing your web site.
