What is 807 gram-weight in dynes?
00:00:06.840 --> 00:00:10.710
Take gravity to equal 9.8 meters per second squared.
00:00:12.240 --> 00:00:15.350
So first of all, in this question, let’s understand what the units are we’re looking at.
00:00:16.150 --> 00:00:19.570
So first of all, we have gram-weight which can also be known as gram-force.
00:00:20.930 --> 00:00:25.880
So what gram-force or gram-weight is, is a gravitational unit of force.
00:00:26.310 --> 00:00:32.810
And what this is, is a force with which a body of the unit mass is attracted by the Earth towards its center.
00:00:34.370 --> 00:00:42.480
So therefore, for a gram-weight or gram-force itself, we can say it’s the force with which a mass of one gram is attracted by the Earth towards its center.
00:00:44.140 --> 00:00:47.640
And if we take a look at a dyne, what a dyne is, is the absolute unit force.
00:00:48.900 --> 00:00:53.960
And this is the force which produces an acceleration of one centimeter per second squared in a mass of one gram.
00:00:55.410 --> 00:01:01.610
So before we can work out what 807 gram-weight is in dynes, what we need to do is take a look at our acceleration due to gravity.
00:01:02.110 --> 00:01:04.740
So here we have 9.8 meters per second squared.
00:01:06.240 --> 00:01:09.250
But in dynes, what we’re looking at is centimeters per second squared.
00:01:09.280 --> 00:01:11.130
So what we’re gonna do is multiply this by 100.
00:01:12.720 --> 00:01:16.190
So when we do, what we get is 980 centimeters per second squared.
00:01:17.670 --> 00:01:22.160
So therefore, to convert from gram-weight to dynes, what we’re gonna do is multiply by 980.
00:01:22.670 --> 00:01:27.100
So 807 gram-weight is equal to 807 multiplied by 980.
00:01:27.360 --> 00:01:28.740
And then the unit will be dynes.
00:01:30.090 --> 00:01:35.140
So this is gonna give us a final answer of 790,860 dynes.
