Document Summary
The normal force is perpendicular to the tangent. As a ball rolls down a hill, it"s speed increases and it"s acceleration decreases. Average velocity = delta x / delta t. A satellite orbiting earth doesn"t fall because: the satellite goes fast and the earth"s surface is curved. Inelastic collision (don"t break apart and move away together) v2 = [(m1)/(m1+m2)](v1) R 1 r 2 r 3 but make sure the sum of r is common denominatored first. Total current = voltage of source / total resistance. Ohm"s law: potential difference (voltage) over and ideal conductor is proportional to the current through it. The constant of proportionality is the resistance (r). 1 coulomb = 6. 24 x 1018 proton charges. Newton"s first law: an object at rest stays at rest and an object in motion stays in motion with the same speed and direction. Newton"s second law: force = mass * acceleration.
