Name: lewton’s Laws Homework 1)What is the amount of force required to keep a 6-kg object that is in outer space moving with a constant velocity of 2 m/sis__N. a. 0.333 b. 2 a3 d.6 f. none 2)The acceleration of an object is related to the net force exerted upon it and related to the mass of the object. In equation form: a = Fnet / m. b. inversely, directly c. directly, directly d. inversely, inversely 3) Understand Newton's 2 Law and answer the following questions A. An object accelerates at a rate of 8 m/s’ when suddenly the net force exerted on it increases by a factor of 2. The new acceleration will be _16_ m/s’. B. An object accelerates at a rate of 8 m/s’ when suddenly the net force exerted on it increases by a factor of 4. The new acceleration will be _32_ m/s? C. An object accelerates at a rate of 8 m/s’ when suddenly the mass decreases by a factor of 4. The new acceleration will be _32_ m/s’. D. An object accelerates at a rate of 8 m/s’ when suddenly the net force exerted on it increases by a factor of 2 and its mass decreases by a factor of 4. The new acceleration will be _64 m/s*, 4) Rank from largest to smallest the acceleration of the objects below.
