Are you agree that your weight is equivalent to the friction force. Why?
No. On a horizontal surface the normal force is equal to weight. If you are moving at constant velocity you only overcome frictional force, which is not equal to weight. This is easier to see on an incline. At some point an object will slide at constant velocity down the incline. This is related to trig functions of the angle of incline multiplied by the weight which is always less than the weight.
What is an example of constant motion?
A ball rolling at a constant speed at the same rate of speed on a still surface.
Does the frictional force depend on the area of surface contact?
No. Frictional force is independant of surface area.
What is surface roughness tester?
surface roughness tester is the machine which used to measure the roughness of the surface using probes... roughness is nothing but the frictional force applied by the surface to the adjacent surface.. if roughness increases the amount of frictional force increases..
Why does weight affect frictional force?
Given an object if contact with a surface, the limiting frictional force is directly proportional to the normal reaction to the weight of the object at its point of contact with the surface.

What is a solid that has 1 flat surface and can roll?
A cone. If your definition of rolling includes the motion of a cone down an incline.

No. Frictional force is independant of surface area.
How much work or energy does it take to push a car up an incline?
The answer depends on a number of factors: - the weight of the car - the steepness of the incline - the frictions of the of both the car to the incline surface and the pusher to the incline surface

What are some examples of a slanted surface or an incline?
In incline happens when a flat surface is higher at one end making it a slanted surface. Examples of inclines include wedges and ramps.
What is a word for a flat slope surface?
It is an incline.
Why does weight affect frictional force?
Given an object if contact with a surface, the limiting frictional force is directly proportional to the normal reaction to the weight of the object at its point of contact with the surface.
Is rough surface better or smooth surface?
The rough surface is better than the smooth surface for the frictional force to act.
What did Galileo discover while under house arrest?
He developed a hypothesis for the motion of physics by using a ball and an incline. He found that when a ball rolls down an incline, it accelerates towards the bottom of the incline. When a ball rolls up an incline, it decelerates. And when a ball is on a flat surface, it moves at a constant speed because a force acts downwards in the vertical direction. As Newton discovered after Galileo died, this particular force is gravity. It is also the force responsible for the acceleration and deceleration of a ball while rolling down and rolling up an incline, respectively.On a double incline, Galileo found that a ball returns to the same vertical height that it was released from. (see what a double incline is, and you'll get it)Also, he found that neither the angle nor the total distance travelled of a rolling ball matters, only vertical height.So in contrast to Aristotle's previous theory that the natural state of objects is at rest, Galileo discovered that the proper state of motion is not at rest, but to continue in its current state of motion. Galileo's experiments with the motion of balls is the basis for Newton's law of inertia (or his first law of motion).
What is the force that oppose motion between surface?
Frictional force
