Question

Two blocks of iron of different masses are kept on a cement floor as shown in fig . Which one of them would require a larger force to move it from the rest position? Write the reason for your choice

Answer 1

answer : block of mass 2 units would require a larger force to move it from the rest position.

according to Newton second law of motion, when a body is moving with an non-uniform velocity {i.e., accelerating motion}, body must experience force. and force experienced by body is directly proportional to its mass and acceleration. Viz, F = ma

now, you can say, if we want to move both the block with same acceleration then, force will be higher for higher mass and lower for lower mass.

for instance,

force on block of mass 2 unit, F = 2a

and force on block of mass 1unit , f = a

here, obviously F > f .

so, block of mass 2 unit would require larger force to move it from the rest position.

Answer 2

one is 1 kg and 2kg if we push both also which will be which is going fast that is the answer example 1kg and 2kg the 1kg will be going friend why because is less quantity but 2kg is the higher quantity so that we can give more effect of ozone that
