Physics Baseline question and answers graded A+ Passed

Physics Baseline question and answers graded A+ PassedWhat is the net force on any object of mass m in free fall near the Earth's surface if there is no air resistance? - correct answer mg (gravitational force) What is the acceleration of any object in free fall near the Earth's surface if there is no air resistance? - correct answer 9.8 m/s^2 Why don't heavy objects in free fall near the earth's surface have a greater acceleration then lighter objects in free fall near the earth's surface. - correct answer a=F/m as m increases F increase - the ratio =g If you strike an object and exert a force on it, what force is that object exerting on you? - correct answer an equal but opposite force What happens to the kinetic energy of an object when its speed is doubled? - correct answer the kinetic energy is quadrupled What happens to the momentum of an object when its speed is doubled? - correct answer the momentum is doubled Imagine you're standing on the surface of a shrinking planet. If it shrinks to one-half its original diameter with no change in mass, how much would you weigh? - correct answer four times your original weight In the question above how much will you weigh if the planet doubles its original diameter? - correct answer 1/4 of your original weight
