To begin, we have that weight is a measure of the gravitational force on an object.
00:24
We have that the normal weight of an object would be the weight at a regularized or regular location, i .e.
00:55
At sea level.
00:56
When an object is in free fall, we can think of this as a situation where...
01:14
Oh, excuse me, i need to back up.
01:16
No, that definition of normal weight is not correct.
01:19
Excuse me.
01:21
The normal weight is the force or the normal force countering gravity, i .e.
01:45
Actually, it'll be easier to illustrate what the normal weight is as follows.
01:53
So we have that weight is the force downwards on an object due to gravity.
01:58
If this is something like, say, you know, it's an apple sitting on a table, then there's also going to be a normal weight due to the equal and opposite normal force.
02:10
The reason why we make a difference between the normal weight or why we consider there to be a difference between the normal weight and the true weight, the gravitational weight, is because we can imagine a situation such as being in an elevator under acceleration...
