Question

. Choose True/False in the following : (i) Apush or pull can always make bodies move. (ii) Force can change the direction of a moving body. (iii) A ball will move a short distance on floor than on grassy ground before stopping.​

Answer 1

Answer:

i) True

ii)true

iii)false

Answer 2

Answer:

i) True

ii) True

iii) False

Explanation:

in i) the push or pull is called a force which gives the body the energy required to move.

in ii) If the magnitude of the force applied on the moving body is greater than the force used to move the body, then using law of vectors the net force will act in the direction of the resultant.Thus force can change the direction of a moving body.

in iii) it is false because a tiled floor is smooth and hence has less friction so a ball will move a longer distance than on grassy ground where friction is high.
