More force for what?


According to Newton's Second Law, F=ma (force = mass x acceleration), it requires more force to accelerate a more massive object.


On the other hand, do some reading, in basic physics books, about friction - even to maintain a constant speed, the force required to overcome friction is also proportional to an object's weight. The force of friction is equal to the "normal" force - the force perpendicular to the surface of contact, multiplied by a coefficient of friction. The coefficient of friction is typically somewhere between 0.2 and 1.0, depending on the types of surfaces.

What law says that heavier objects require more than lighter objects to move or accelerate them?

Newton's second law of motion states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This means that heavier objects require more force to move or accelerate them compared to lighter objects.


Why are heavier objects harder to start or stop moving?

Heavier objects have more inertia, which means they resist changes in their motion. More force is needed to start or stop the motion of a heavier object compared to a lighter one.


Which body moves faster heavier or lighter?

In a vacuum, all objects fall at the same rate regardless of their weight due to gravity. However, in real-world conditions with air resistance, lighter objects tend to fall slower than heavier objects because air resistance affects lighter objects more.


Why is A heavier objects harder to accelerate than a lighter object?

A heavier object has more mass than the lighter object.The acceleration of any object is (force on the object) divided by (the object's mass).A = F/MAs this simple fraction shows, if equal forces were applied to many different objects, you'd immediately see that the smaller an object's mass is, the moreacceleration results.


Is it easier for a tornado to lift heavier objects or lighter objects?

Tornadoes are more likely to lift lighter objects as they generate an upward force with their strong winds. Heavier objects may be more difficult for tornadoes to lift unless they are caught in the vortex of the tornado's winds.

The 2nd Law of Motion by Sir Isaac Newton.


How are speed and weight related?

Speed and weight are related in that a heavier object requires more force to accelerate or decelerate, thus affecting its speed. In general, heavier objects tend to have lower speeds due to the increased force required to move them compared to lighter objects.


Does a heavier object have more inertia than a lighter object?

Yes, inertia is the tendency of an object to resist changes in its state of motion. Heavier objects have more inertia than lighter objects because they require more force to accelerate or decelerate.


Does it take more force to move heavier objects than lighter objects?

All other factors being Equal, Yes. This is even true in Space where the objects 'may' be unaffected by Gravity and WEIGH Zero. The critical factor here is MASS, which we commonly call WEIGHT on the Earth. The MASS of an Object does not change based on its POSITION. The WEIGHT of an object varies based on its Position relative to a Gravitational body, such as the Earth.


Does a heavier object or a lighter object experience a greater gravitatoinal force?

Why do lighter objects fall slower than heavy objects?

Lighter objects fall slower than heavier objects because they have less mass, which results in less gravitational force acting on them. This means they experience less acceleration and take longer to reach the ground compared to heavier objects. The acceleration due to gravity is the same for both objects, but the heavier object requires more force to overcome its weight and accelerate at the same rate.


Does a heavier object or a lighter object experience a greater gravitational force?

A heavier object experiences a greater gravitational force than a lighter object, as the force of gravity is directly proportional to the mass of an object.
