When you include the effects of friction, it takes less force to move a light-weight object. If you can get the objects into a frictionless environment, then any force, no matter how small, can move any object, no matter how heavy.
Net sum of all forces are zero .............
It can make moving heavy objects easier for example sliding friction you can slide it or rolling friction you can roll the object across some kind of round cylinders or even fluid friction with water running under the object can make it easier.
Friction is most commonly known as any push or pull. There are four types of friction ; sliding friction, static friction, rolling friction, and fluid friction. Sliding friction is when something is sliding against another surface. Static friction is when there is force being applied upon a heavy object or the object is being moved on a rough surface. Rolling friction is when something is rolling on a surface and friction slows it down. Finally, fluid friction is when an object is being slown down on or in water, air, or any others fluid.
Static friction is the friction that acts between two objects which are not moving in relation to each other. For example, it is the force that prevents you a block from sliding down a ramp with a small incline. Dynamic friction is the friction that acts between two objects which are moving in relation to each other. For example, it is the force that makes pushing a heavy box across the floor difficult.
When you move a heavy object, you must apply a lot of force before the heavy object begins to move. This resistance you feel while the box is NOT moving is static friction. Static friction opposes movement in an initially non-moving object.

If it doesn't budge, the net force must be zero. What usually happens is that there is a force of friction that opposes the push or pull; as you pull harder, the force of friction increases. At a certain treshold, there is not enough friction (it can only increase to a certain level), and the object starts moving.

The large body will have a strong force of opposing friction, related to its large weight. The force of friction between two materials is equal to the normal (perpendicular) force between them, times a factor (the so-called coefficient of friction), which depends on the materials, but is typically less than one.

friction opposes the force causing the body to move. fiction is the reason why you are unable push very heavy objects on normal surfaces. if an object is on a truly frictionless surface, you will be able to push it left to right, side to side regardless of how heavy it is.
Water helps lift an objects via the buoyancy force. The buoyancy force is equal to the weight of water displaced by the volume of the submerged object. If this buoyancy force is equal to the weight of the object, the object will float in that position. If the object is completely submerged and the resulting buoyancy force is less than the weight of the object, it will continue to sink.

When heavy objects roll down something, fricition is involved. Friction is made by the rubbing of one thing against the other. Try rubbing your hands together reallly fast. Do your hands feel warm? Heavy objects have more friction, which slows down the heavy object. Lighter objects have less friction which cause it to run faster.
