Forces and Laws...

A vehicle is moving on a rough road in a straight line with uniform velocity. Then

A force acts on an object which is free to move. If we know the magnitude of the force on the object and the mass of the object, Newton's 2nd law of motion enables us to determine the object's :

A and B are two objects with masses 6 kg and 34 kg respectively. Then,

A stone is tied to the middle of a string and suspended from one end as shown in the given figure. Here S is the stone and O is the point of suspension. If you give a sharp jerk at P, the string will break :

If you are asked to push an object so that the acceleration produced in it has to be twice as before, then the force required will be :

The law which gives a quantitative measurement of force is :

A cricket player while taking a catch lowers his hands to :

$$P$$ and $$Q$$ are two objects with masses $$5 kg$$ and $$30\ kg$$ respectively. Then:

The process of walking involves:

Which of the following represents the SI unit of force?
