00:02 In the question number 1, it has been given that kinetic energy is directly proportional to mass of the object and the square of each velocity.

00:10 This option is correct.

00:12 That is, this is true.

00:14 Now coming to the option number 2, that is, kinetic energy is a vector measurement because it has both magnitude and direction.

00:23 This statement is wrong.

00:25 This is false.

00:27 Because kinetic energy is a scalar quantity and it doesn't has any direction.

00:34 The third option that the kinetic energy doubles if you double the mass is correct.

00:41 It is true.

00:47 Now coming to the fourth one that the object that has kinetic energy are not moving.

00:51 This is wrong.

00:53 This statement is false.

00:58 Now the fifth one is if the work done on an object by non -conservative force, then object will either gain or lose kinetic energy.

01:09 This statement is true.

01:14 That is the statement number 5.

01:17 Now the 6th one is an object has a kinetic energy of 40 joules.

01:22 If its velocity twice as much, then its kinetic energy would be 80 jule.

01:27 This statement is wrong because kinetic energy is given by half mb square.

01:33 So if v changes to 2v, then the overall kinetic energy change will be 4 times the original.

01:39 So it will be 4 times of 40, that is 160 jule...
