Let's consider the following statements and see which are true.
00:06
There are two forces acting on an object, and the sum of those forces is equal to zero.
00:11
Then the object is not moving.
00:14
Well, while we can have two forces, which when you sum them up is equal to zero, net force is equal to zero, that means that the acceleration is also equal to zero.
00:29
But this cannot factor in that there could be.
00:34
A non -zero velocity.
00:39
If there's any velocity, in fact, then this is disproven.
00:44
So therefore, this is not true.
00:48
There are two forces acting in an object that is accelerating north.
00:54
At least one of those forces must point north.
00:57
So if we have an object that's accelerating to north, at least one of those forces must point north.
01:10
This is also not true...
