Want this question answered?
yes
the INITIAL velocity does not change. It is constant. however, the velocity changes depends on the friction and inclination of the inclined plane.
It doesnt. I assume you mean angle, and as the angle increases the frictional force creases as friction is dependant upon the force of the normal. When the angle increase's the force of the normal decreases (because it is a cosine function).
As liquid flows on an inclined surface there will be frictional force between the bottom most layer and the surface of inclined plane. More over there will be a friction between the successive layer of the liquid. This is termed as viscous force.
An inclined plane reduces friction when kinetic energy is present. If the object is in motion down the ramp, then there would be gravity assisting it downwards. The normal force would decrease, as well as the friction. For rough surfaces there usually is more friction than smooth surfaces. For instance, if a car travels on an unpaved road, it travels slower due to friction. Compare that to a paved road and the car moves a lot faster.
cause my mommy says soo
ignoring friction or ideal mechanical advantage
While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane. Overcoming that friction is work done which is totally wasted.While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane.

gravity and friction
yes
the INITIAL velocity does not change. It is constant. however, the velocity changes depends on the friction and inclination of the inclined plane.
The ideal mechanical advantage, or IMA, of an inclined plane is equal to the length of the incline divided by its height. The IMA is calculated without regard to friction.
Input force is lost due to friction.
It doesnt. I assume you mean angle, and as the angle increases the frictional force creases as friction is dependant upon the force of the normal. When the angle increase's the force of the normal decreases (because it is a cosine function).
Reduce the friction
smaller
Yes, a hammer is a inclined plane. It's head, is the inclined plane.
