Ah I see now, I've just assumed since I'm increasing my speed by 70m per sec, 10 seconds later i would have to simply multiplty the 10 by 70 to get the distance, so stupid...:redface:
Thank you mentor, I'm quite clear on the acceleration and the meter squared concept now:biggrin:
That's great explanation phyzguy, I've find all these mathematic concepts always much easier to learn by real life examples! I really like the idea of using each second as opposed to per second per second, my head just can't seem to cope with this type of sorcery! I'll just go with per second...
So let's say I start driving and when i reach point a, my speed is 50 m/s and it stays constant.
Case 1: 10 seconds later, I'm 500 meters away from point a, acceleration = 0.
Case 2: I accelerate by 70 m/s per second, 10 seconds later, I would've been 700 meters away from point a?
What is the concept of per second per second?? Like acceleration??
I'm in my final year of college and I'm struggling to get a clear idea on the concept of per second squared. I mean a meter per second yeah that's understandable, it's just mean your moving a meter per second, so 5 seconds...
Sorry for the late reply man, I was bogged down by all the lab questions yesterday. Anyway back to the topic, I certainly hope that the spring wouldn't contribute to the wave since it's first purpose was just there to make sure the paddle doesn't fall all the way back since there's enough space...
Although the paddle is being pulled in the upright direction, the paddle itself actually moves in more on the x-axis. Here's a video to help visualize the thing in motion:
I remember doing system modelling in 2nd year, and I think the equations are much more complicated than those i listed...
Well, in this case, the 0.315^3 = 315 litres of water, which means it has 315 kilograms (693 lbs), if we have to lift it vertically upwards, then we're going to need at least 693 lbs??
Hi R, sorry for the late reply, it's been q long day for me. Ok, let's get back to your questions. Yeah as you can see the motor will have to have to rotate to pull the string, which in turn pull the paddle in the purpple arrow direction, so it will have to go against the spring. The spring...
1. Ok I have to build a real life wave-maker for my Final Year Project(FYP). My wave-maker design is as shown below:

The proffessor said I need to be able to calculate the torque of the motor before I order it. I start out by calculating...
