While moving a heavy object how can you decrease the frictional force?

Use round wheels to roll the load, lighten the weight by removing attached or contained objects, or place a smoother surface betwen the object and the floor.
Water or other fluids can be used to decrease the resistance, but only if they remain between the object and the floor.

Why do some objects move so fast and some move so slow?
The speed with which an object moves depends on its mass, any force applied on it (including frictional forces, which slow it down), and its previous history - i.e., if it has been moving before, it will have the tendency to continue moving, at least for a while, until frictional forces slow it down.
Do objects have inertia only when they are moving?
Inertia is the tendency of an object to resist a change in motion. An object would have inertia while moving and also while at rest.
What is the difference between collided into and collided with?
Collided Into would be with a stationary object while "with" would be with another moving object.
How does friction make you stop on ice?
Newton's first law states that a body in motion will remain in that same motion unless acted upon by a force. If a mass is sliding on the ice it exerts a force down upon the ice. There is a frictional force is the one that acts to slow the mass down, and it is equal to a coefficient of the frictional surfaces X the downward force upon the surface. While ice, especially smooth ice will contribute to a small coefficient of friction as opposed to concrete or wood the effect is there. This frictional force of ice exists and will act to slow down the object. The heavier the object the faster it will be able to be slowed down. And the substance of the object contributes to the coefficient too. All according to the laws of Newton. It should also be mentioned that the coefficient of friction between the ice and the object depends of lots of things besides the smooth ice, such as the material that is moving the ice, the temperature of both ice and the moving object, any surface films such as water or oil etc.
What is the brakes are applied on a moving carthe frictional partsbrakes or are forced against the rotating parts of the carbrake or?
the partsbreaks are is better than much of most things cant feel while being used.

Does the distance from the sun increase or decrease while moving away from the equator?
Increase

How do you focus while others are communicating?
try to block them out by focusing on a non moving object
Is it possible that an object moving in certain direction with an accleration in the perpendicular direction?
yes. this is the baseline understanding for rotational motion. Think of driving a car, if you turn the wheel of the car then you are directing the frictional force near perpendicular to your velocity and thus "turn" the car. More precisely, the car's acceleration is radial while its velocity is tangential and thus the car is following a rotational path, during the turning phase of travel.

What does the dragging mean and how do you do it?
It involves moving the cursor over an object, selecting it, and moving it to a new location. If you are using a mouse, you can drag and drop an object by clicking the mouse button to select an object, then moving the mouse while keeping the mouse button pushed down. This is called "dragging" the object. Once you have moved the object where you want to place it, you can lift up the mouse button to "drop" the object in the new location.

Does an object always move in the direction of the unbalanced force exerted on it by another object?
Not always, the unbalanced force only points in the direction of the acceleration so a body may be moving in the opposite direction. Example. A car moves with some speed to the right on a horizontal surface and lock the brakes, if the surface has friction, but the net force acting on it is equal to the frictional force pointing left and produces a Deceleration of carriage until stop, but while this happens continuously in motion to the right.
