The frictional force on a sliding body on a plane will be acting parallel to the plane against the motion of the body. But the magnitude of the (kinetic) friction force is proportional to the weight component normal to the plane. The weight component parallel to the plane is the force that tends to slide the body down the inclined plane. When the sliding body has acquire steady velocity, the friction force is equal to the body's sliding force.
Torque is a force times a distance (the distance from the rotation axis where the force is applied). The angle at which the force is applied can also play a role. It is not directly related to speed.Torque is a force times a distance (the distance from the rotation axis where the force is applied). The angle at which the force is applied can also play a role.

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).

Kinetic friction is commonly thought of as the friction between two objects while those two objects slide against each other. To determine the coefficient of kinetic friction (for an object under the influence of gravity on some surface), one needs to determine the angle at which the sliding object moves at a constant speed down the other object (think of a flat piece of rubber sliding down a flat plank of wood). This is different from static friction where the sliding object has some applied force to move along a surface, but that object is stationary because of the friction applied by the surface. To determine the coefficient of static friction, one needs to determine the angle at which the sliding object begins to move down the surface.
The applied force will depend on the required force, and the angle to the ramp (or the horizontal) at which the force is applied.
I usually adopt a frictional angle of 40° to 42°. I've seen some books suggesting 47° to 51° depending on the type of granite.

The energy efficiency increases as the angle increases.

Take a ball and push it an angle yo direction of motion.what do you observe? Answer-change the angle of your hand with respect to the direction of motion of the ball.Does yoo effort result in change in direction of motion of ball?
Yes. The angle is the direction of the vector, so if the angle changes, the direction changes.

Reflection is a change of the angle of light without a change of medium. Refraction is a change of the angle of light with a change of medium.
