Hi, this is a true or false question based on momentum.
00:03
10 statements are given.
00:05
Let's take one by one.
00:06
First sentence says that an object that is moving with constant velocity will have momentum.
00:14
As per formula, momentum is p is equal to mb product of moss and velocity.
00:21
Hence this statement is completely true.
00:24
Any object that has velocity will have momentum, whether it is constant or variable.
00:29
Second says that momentum of an object varies directly with its velocity.
00:38
This is also completely true.
00:43
As per formula p is equal to mv.
00:45
So we can directly relate momentum and velocity.
00:48
Third sentence is given that momentum of an system is during elastic collision, it is concerned.
01:00
The momentum, the total momentum of a system during a system.
01:03
Elastic collation is concerned and in inelastic it is not concerned this is a given statement this statement goes wrong as the total momentum of the system is always concerned always momentum is concerned in both elastic and inelastic collation as per law of conservation of momentum 4th it is given that kinetic energy of a system is conserved in inelastic collision in inelastic collision kinetic energy is conserved but in elastic collision kinetic energy of the system is not concerned as per this given statement it is given wrong so the sentence goes wrong because kinetic energy is conserved in elastic collision and it is not conserved in elastic collation.
02:16
5th sentence given that lesser the mass of an object, lesser will be its momentum.
02:26
So a less massive object cannot have more momentum as a given statement.
02:31
Momentum is moss into velocity.
02:36
So even if m is less, p is directly related to v.
02:42
Even a less massive object can have high velocity.
02:47
Thereby momentum of less massive object also can be higher if its velocity is more.
02:56
Hence the given statement is false.
02:59
Next, it is given that if an object.
03:03
Travels in the east so its velocity is pointed towards east but it slows down.
03:12
This given that momentum of that object will be towards west...
