the gradient of the slope
The channel roughness
The amount and size of bed load
By using kinetic friction
Weight affects friction by increasing the force pressing the surfaces together, resulting in more friction. Mass does not directly affect friction, but it influences the normal force, which in turn affects friction. Generally, higher weight or mass leads to higher friction.
no, friction just changes the motion of an object.
if there is friction on the hill it will slow you down
it affects motion by friction a friction pull it down or up
Mass affects friction by increasing the normal force between the surfaces, which in turn increases the frictional force. Surface type affects friction by altering the coefficient of friction between the surfaces - rougher surfaces typically have higher coefficients of friction which results in greater frictional forces.
Friction acts in the direction opposite to that of the net force acting on the object.
Friction affects most every thing. In a mechanical metronome you would not need a power source if there were no friction.
it affects it by the contact with the car
If the river doesn't provide spate, the farmer couldn't cultivate anything in the field. Thus river affects the life of a farmer.
The speed of a river is affected by the amount of friction slowing down the water and the grade or fall of the river. The amount of friction is determined by how rough the bed or wetted perimeter is, and how big the perimeter is. A wide shallow river or a very deep and narrow river with the same volume and grade will be in contact with similar areas of river bed, causing the same amount of friction. But a river with a semi circular shape in cross section and the same volume and grade will have less contact area with the river bed and will therefore have less friction and be faster. The steeper the grade of the river, the faster it will flow.
