Why is a heaver object harder to accelerate than a lighter object?
The difficulty to accelerate an object is related to its mass, not to its weight. However, on Earth (i.e., more or less constant gravity), mass and weight are also proportional. As to "why", I believe that is still an area of active research. We know that there is a property called mass, that causes gravitation, and inertia (i.e., a resistance to acceleration), but the exact nature of this property is still being studied.
When an object is in water is it heavier or lighter?
When an object is in water, it may appear lighter because of the buoyant force acting on it. The buoyant force counteracts the weight of the object, making it feel lighter in water compared to in air.
Does the weight affect the acceleration?
Yes, weight does affect acceleration. In general, objects with greater weight require more force to accelerate compared to lighter objects. This is due to the relationship described by Newton's second law, which states that the acceleration of an object is directly proportional to the force applied and inversely proportional to its mass.
Why does a heavy object feel lighter when under water?
A heavy object feels lighter in water because the upward buoyant force exerted by the water opposes the force of gravity acting on the object. This buoyant force counteracts the weight of the object, making it feel lighter.
Is weight a force, and if so, how does it affect the motion of objects?
Yes, weight is a force caused by gravity pulling on an object. The force of weight affects the motion of objects by influencing their acceleration and speed. Objects with greater weight experience stronger gravitational pull and therefore may move slower or require more force to accelerate compared to lighter objects.

How does weight factor in when determining buoyancy?
The lighter a certain object is, the more likely it is to float, if the object is heavier, the object will sink.

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.
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.
Why is there a difference between the weight of an object in the air and it's weight in water?
Because of buoyancy ; something that acts in the opposite direction to the force of gravity to make the object feel lighter.
What is the relationship between mass and a object?
Assuming the only difference is mass and that two objects have the same shape and size, it will take longer for the heavier object to reach terminal velocity than the lighter object. The terminal velocity of the heavier object is greater than that of the lighter object. Since the two objects accelerate at nearly the same rate at slower velocities, the time to reach terminal velocity will increase as weight or mass of the object increases. However I would not expect the increase to be a linear proportion since the drag is proportional to the square of the velocity.
How does weight have to do with mass?
Weight is the force of gravity acting on an object's mass. Mass refers to the amount of matter in an object, while weight is the force exerted on that mass due to gravity. The weight of an object is directly proportional to its mass, so a heavier object will have a greater weight compared to a lighter object of the same mass.
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.
