Why does it take more force to accelerate a more massive object?

A force will not increase or decrease an acceleration. If the force is constant, it will cause a constant acceleration. It may increase or decrease the speed. The change of velocity - for the same force - is the same, whether the speed is increasing, decreasing, or just changing direction.

∙ 14y agoNewtons second law of motion states that the force applied on an object is equal to its mass multiplied by its acceleration. In mathematical terms, this law can be stated as F=ma . Therefore, if the objects acceleration is considered constant, according to the previous equation, the amount of force applied on an object is directly proportional to its mass. In other words, if object A is three times as massive as object B, object B is accelerating at a constant rate because of a force applied on it, and you want to apply enough force on object A so that it can accelerate at an equal rate to that of object B, them you have to apply three times as much force on object A as is being applied on object B.
A non mathematical reason for why this happens is because mass gives objects a quality known as inertia. Inertia is the resistance an object offers against a force that tries to move it. therefore, if an object is more massive, it will offer more resistance against any force applied on it, so you will have to apply more force in order to move it. Its a bit like how its a lot easier to push an empty swing than it is to push a swing with someone sitting on it (this might not be the best example though, as there are other factors that apply in this situation, although it helps to express the basic idea).

The force required to slide an object is equal to?
The force required to accelerate an object depends on the object's mass. Newton's second law states that Force = Mass * Acceleration. Re-written to solve for acceleration, this becomes Acceleration = Force/Mass. Basically, this means that the more mass an object has, the more force is required to accelerate it. Also, the faster you want to accelerate the object, the more force you will need.
Can force stop motion?
if you put force on an object, in the opposite way it is moving. force makes an object with mass accelerate. if the force you put accelerates it enough it will stop spontaneously, or else it will stop slowly. if that first type of motion was created by force, and i mean the force is still forcing the object to move, then u have to put more force to the object in the opposite direction in order to stop it. F= m*a where F = force , m= mass , a= acceleration hope u got ur answer
Is more force is usually required to pull an object than to lift it?
Heavier (more massive) objects require more force to move than lighter objects. The formula is F = ma (force is equal to mass times acceleration). The same force applied to a more massive object will provide less acceleration (motion).
What is the definition of a unbalanced force?
There is no such thing as "an unbalanced force". There are only forces. When two or more separate forces act on the same object, the GROUP of forces may be balanced or unbalanced. If the sizes and directions of all the individual forces add up to zero, then the GROUP of forces is balanced. If one of them changes or goes away, then the GROUP of forces is unbalanced.
Is the force of gravity greater on more massive objects?
Yes. According to Newton's Second Law, force is the product of mass and acceleration. F=m*a The acceleration for every massive object is the same near the earth's surface, regardless of its mass. This is why two objects will hit the ground at the same time, even if they have different mass, as long as air resistance isn't a problem. One way to think about it is this: heavier objects have more inertia, so gravity has to use more force to get it to move at the same acceleration as a lighter object.
How is motion of an object affected when force acts on it?
If a force is exerted on an object, it will accelerate in inverse proportion to its mass in the direction of the force. For example, if two objects of different mass are subjected to the same force, the less massive object will accelerate more.
What affect does mass have on acceleration?
this equation might help force = mass * acceleration the more massive an object is the more force is required to accelerate it
If a constant force acts on two object's of different masses which object will accelerate more?
Force = mass times acceleration, so the smaller mass will accelerate more.
If the same force is constantly applied to two movable objects what will the more massive one do?
If the same force is constantly applied to two movable objects, the more massive one will accelerate. Also, the more massive one will accelerate more slowly than the less massive one.
The same force is constantly applied to two movable objects the more massive object will?
Accelerate less than the object with the smaller mass, as per Newton's 2nd Law.
The force required to slide an object is equal to?
The force required to accelerate an object depends on the object's mass. Newton's second law states that Force = Mass * Acceleration. Re-written to solve for acceleration, this becomes Acceleration = Force/Mass. Basically, this means that the more mass an object has, the more force is required to accelerate it. Also, the faster you want to accelerate the object, the more force you will need.
The force of gravity on a 4kg object is twice that on a 2kg object Why does the 4kg object not fall with twice the accleration?
The reason that a heavier object does not fall faster even though there is more gravitational force on it is because it has more mass, and more energy is required to accelerate the greater mass. A small mass doesn't need a lot of force on it to accelerate it. It's "light" in weight. But a heavier one needs more force on it to accelerate it equally. Want a heavier object to accelerate the same as a lighter one? Apply more force. Gravity does that. Automatically. Think it through and it will lock in.
How can an object accelerate if it is moving at a constant speed?
by adding more force
Why do two objects with different mass will fall at the same time?
-- It takes more force to accelerate an object with more mass. ... Gravity exerts more force on an object with more mass. -- It takes less force to accelerate an object with less mass. ... Gravity exerts less force on an object with less mass. Whatever the mass of the object happens to be, gravity always exerts just the right amount of force to accelerate it at always the same rate ... 9.8 meters per second2.
Which object will accelerate more if the same force is applied to both a pickup truck or a trctor-trailer truck?
Whichever is lighter will accelerate more quickly.
Does a more massive object weigh more than less massive one?
If the force is gravity, the answer is yes. Gravity "pulls" on an object in proportion to its mass. A heavier (more massive) object is pulled on by gravity more than a lighter (less massive) object. A football tackle is pulled on by gravity more than the average grade school student.
What kind of force do you need to stop a more massive object?
inertia
