That depends on the situation. But more massive and heavy objects are typically more difficult to move around quickly.
f =V x m x a
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
No. The speed of the object does not affect the amount of friction between an object and the surface. Friction is affected by the types of surfaces in contact, smoother surfaces produce less friction, and the weight of the object moving horizontally affects the resistance relative to the two surfaces in contact. Greater weight causes greater resistance.
mass
yes, and the speed depends on the weight of the object

Circular motion would change the direction of an object but would not affect the object's speed.
It depends... the object could be falling, going straight, going uphill or going downhill.
mass

Yes, when the object is submerged in water then water exerts opposite buoyonci force which decrease the weight of object.
Gravity affects weight, it does not affect mass.
No it does not, but it might affect the volume of the object (it might shrink or expand).
Yes
