Why is this statement correct? "The more the massof an object, the more force needed to move it".?

Question

Explain in scientific terms please ...

Answer 1

Force = mass times weight. On earth the mass is constant, because the gravitational pull is constant.

So the amount of force needed to move an object that is at rest, depends upon the mass. In other words the heavier the object, the more force needed begin motion.

HOWEVER!.....there is one more factor that is neglected by the above equation. Newton, tended to do that, most of his laws only apply in a vacuum and on frictionless condition.

That other factor is the coefficient or friction.
On ice its low...and take less force to set an object into motion.
On sand paper the coefficient is high!

RECAP!
Heavier objects on rougher (higher coefficient of friction) surfaces are more difficult to set into motion.

GOOD LUCK!

Answer 2

First of all it's mass X ACCELERATION that equals force (F = Ma), not X velocity as one answerer put it.

Thus, if F = Ma, and we double the mass to 2M, the force becomes 2F = 2Ma; so it would take double the force (the 2F) to move (accelerate) that doubled mass at the same rate of acceleration.

On the other hand, we could double the mass and keep the force the same F as before. What would happen then? If F' = 2Ma', then a' = F'/2M and the original F = Ma; so that a = F/M.

To compare the a' and a accelerations and find out what the new acceleration (a') would be if we kept the same force, we do a ratio a'/a = (F'/2M)/(F/M) = (F/2M)/(F/M) = 1/2. Then a' = a(1/2); in other words, if we double the mass and keep the force at F, the new acceleration (a') will be half the rate of the old acceleration (a).

The lesson to learn here is that the force is proportional to the mass of an acclerating body. Also note that it is in fact mass, not weight, we are talking about here. Finally, note that the direction of the acceleration and of the force causing that acceleration is in the same direction.

Answer 3

Its really a restatement of an axiom - in other words, it is not deduced, it is stated. Subsequent observation then supports the observation and deductions made from it.

In this case the axiom is from Newton's laws. The force needed to achieve a given acceleration depends linearly on mass.

Answer 4

that's greater durable to push an merchandise on a coarse floor than a gentle one because of the fact which you're able to triumph over the frictional forces between the object and the floor because of the fact that they're opposing your pushing tension. subsequently to make the object pass you're able to push greater durable than the frictional forces. The greater suitable those frictional forces are then the greater durable you're able to push. of direction all of us be responsive to from adventure that gadgets push greater straightforward over gentle surfaces than tough surfaces so the frictional opposing forces could be greater advantageous the rougher the floor gets.

Answer 5

Its Just Newton's Law.

F= m . a
(Forec = Mass X Accleration)

As you increase the mass, you need to give lot of force....

In simple words, You can Kick a foot ball easily than a Heavy stone..

Will this helps you?

Answer 6

According to newton's first law of motion Force is directly proportional with the mass of the body.So more the mass more the force required to move it

Answer 7

F = ma says Newton

F=Force
m=mass
a=accelaration

understand?

Answer 8

because of the principal of inertia.inertia is a sum of other forces[gravity,friction,etc]inertia cases"an object at rest to stay at rest"and"a object in motion tends to stay in motion".the more mass an object has,the more inertia it has.the More inertia an object has, the more force is needed for it to change its state of motion[stop,go]

Answer 9

Because mass an energy are positively related. Remember E=mc2 ?

So a mass of say rock represents an equivalent amount of energy.

So if a mass is increased in size. it represents a larger amount of equivalent energy. Therefore it will take a larger amount of energy to move the mass.

Answer 10

no the correct term is "the more massive an object, the more force needed to move it."

This is stated through the force equations.
Force=mass*Velocity

IF mass increases, forces also porportionally increases.
