ROTATION OF A RIGID BODY
Hello! Welcome back my readers :) are you enjoy your holiday very much? I hope so.Before I
explain about the topic in physics subject, I want to ask do you like Physics subject? It is your friend or your killer subject? For me, I hate physics subject. I always get D in examination . I am trying so hard to get good result in this subject start form semester 1 because, my real ambition is to be a veterinary. Unfortunately , I got module 2 in matriculation and sadly I have to learn Physics . Physics is so complicated if we do not explore . So, in this year I try my best to get Physics subject is A. Now, I love physics subject very much. I hope this 2 semester, I can get
c and above in UPS. What a long story is it? Okay lets talk about this topic . I want to write about this topic because on Wednesday, I have an urban test .So, I can study this subject through this blog . Lets start our lesson guys!
TORQUE(τ)
Do you know what is torque? If you can see why the door is open and close, how the force exerted when the door is open or close?So this is the aim of torque. When we calculate toque , it become this:
τ = F d
F : magnitude of the force
d : perpendicular distance (moment arm)
where τ : magnitude of the torque
F : magnitude of the force
d : perpendicular distance (moment arm)
where τ : magnitude of the torque
TORQUE ALSO THE PRODUCT OF FORCE,RADIUS AND ANGLE (SIN 0)
*It is a vector quantity.
*The unit of torque is NM,When the object is:
*The unit of torque is NM,When the object is:
Negative - turning tendency of the force is clockwise.
