They are two different things.
'Mass' is the amount of stuff that an object is made of. Mass never changes.
'Weight' is the force of gravity between the object and some other body.
Of course, 'weight' usually involves the earth. But it's important to understand that if you
take the same object to the moon or to another planet, it still has the same mass, but the
weight will be different over there. It may be more, or it may be less.
"One kilogram" is a mass. It weighs about 2.2 pounds on earth. If you take it to the moon,
it's still the same one kilogram, but up there it weighs about 6 ounces. On Mars, it would
weigh about 13 ounces, and if you could take it to Jupiter, it would weigh a little over
5 pounds there. But it's still the same one kilogram of mass everywhere.

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.
Dose a heavier or lighter object have a greater kinetic energy?
Kinetic energy depends on mass, and speed. Since you can't easily change an object's mass, you would basically change its speed.
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 mass affect the distance an object can travel when catapulted?
well yes it does the heavier the object being launched it wont go as far as the lighter one
Why is it harder to stop heavier objects?
If object "A" is heavier than object "B", then object "A" also has more mass (weight = mass x gravity, and gravity can be assumed to be constant for most practical purposes). And more mass causes more inertia - inertia is the direct result of the amount of mass.
Could the mass of a lighter object be more than that of a heavier object?
No, unless you compare objects on different planets. Weight = mass x gravity, so if gravity remains constant, more mass means more weight.
What both objects are made of the same material but the heavier object floats but the lighter object sinks?
If the object sinks or floats depends on mass or weight. The object can be made of the same material, but if the weight is not the same (say if it is heavery than water) it will sink.

What does changing the mass of an object do the the force of an object?
F= ma Heavier objects require larger forces to move them ! Likewise, Lighter object require small forces

How does something float?
For a certain thing to float, it depends on the mass, weight and the size, . The lighter and smaller a thing is, the more its likely to float. The heavier an object, the more it is likely to stay on the ground. An object can float(or sink) in water, or even in the sky.
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.
