What Does Thoreau Mean When He Says Let Your Life Be A Counter Friction To Stop The Machine? What does Thoreau mean when he says let your life be a counter friction to stop the machine? He urges the reader to be a “counter-friction” to the machine and not to participate in the wrong. Thoreau
What Are The Applications Of Newtons Law Of Motion? We always see the applications of Newton’s second law of motion in daily life when we try to move an object, like stopping a moving ball rolling on the ground, or pushing a ball to get it to move. Reducing the weight of racing cars to
Does Friction Go In The Same Direction As Motion? Does friction go in the same direction as motion? ? (Remember that friction always acts in the direction opposite that of motion or attempted motion between surfaces in contact.) Does friction occur in the same or opposite direction of motion? Friction is an important force because
Does Material Affect Friction? Does material affect friction? The frictional force does not depend on mass or surface area. All that really matters is the types of materials that are in contact. Why does surface material affect friction? Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects
Does Mass Affect Normal Force? Does mass affect normal force? This force is proportional to the mass of the two interacting objects, and is inversely proportional to the square of the distance between them. The factors G M / r2 are the same for all masses at the surface of the Earth. What factors affect
