Answer: Work W = F x d = 10 x 5 = 50 J.
Answer: Period T = 2pi sqrt(L/g), depends only on length and gravity.
Answer: Hooke\'s Law: F = kx, where k is spring constant and x is displacement.
Answer: F = Gm1m2/r2, proportional to the product of masses.
Answer: Escape velocity from Earth is approximately 11.2 km/s.
Answer: For every action, there is an equal and opposite reaction.
Answer: Kinetic energy equals one-half times mass times velocity squared.
Answer: At maximum height, the object momentarily comes to rest.
Answer: Momentum p = mv = 5 x 3 = 15 kg m/s.
Answer: Force has both magnitude and direction, making it a vector.
Answer: Power is the rate of doing work, P = W/t.
Answer: Impulse has units of Newton-second, equal to change in momentum.
Answer: h = 1/2 gt2 = 1/2 x 9.8 x 1 = 4.9 m.
Answer: Standard acceleration due to gravity is 9.81 m/s2.
Answer: Circular motion requires centripetal acceleration toward the center.
Answer: Zero net force means the object is in translational equilibrium.
Answer: Newton\'s Second Law states force equals mass times acceleration.
Answer: Newton is the SI unit of force, defined as kg m/s2.
Answer: Friction always opposes the relative motion between surfaces.
Answer: Moment of inertia of a solid sphere is 2/5 MR2.
