Correct Answer Fg= G m1m2/r^2 where G is the universal gravitational constant What is static friction and what is the formula? Correct Answer -Exists between a stationary object and the surface it rests up Ff ≤ μsN What is kinetic friction and what is the formula? Correct Answer Ff = μk N -Exists between a sliding object and the surface over which the object slides Which value, coeff of static friction or kinetic friction, is greater? Correct Answer coefficient of static friction is always greater What is newtons third law? Correct Answer For every action, there is always an opposed but equal reaction What are the big three equations for linear and projectile motion? Correct Answer x = x₀ + v₀t + ½at² v =v₀ + at v² = v₀² + 2a(x - x₀) Objects that are moving in a circular path are kept from breaking out of the path in a linear direction along the tangent because of the ________________ Correct Answer Centripetal force What is the equation for centripetal acceleration?
