Directions: On this worksheet you will examine the properties of force vs time (impulse) and force vs distance (work) as they apply to two objects of different masses.
Question 1 Two masses, 3 kg and 6 kg, initially at rest, are both pushed by equal forces through the same distance across identical frictionless surfaces. Which mass would experience the greater acceleration?
Question 2 Which mass has the greater final velocity?
Question 3 Which mass gained the greater amount of kinetic energy?
Question 4 Which mass received the greater impulse?
Question 5 If each mass was pushed by a 30-N force through a distance of 78 meters, what is the ratio of the change in momentum of the 3-kg mass to that of the 6-kg mass?
Question 6 What is the final velocity of the 3-kg mass?
Question 7 How much time was required for the 6-kg mass to travel the entire 78 meters?
Question 8 Which formula correctly relates an object's kinetic energy and its momentum?
Question 9 Regardless of which mass is being examined, which graph will always has the greater area?
