Impulse and momentum - Study guides, Class notes & Summaries

Linear Momentum and Collisions ANSWERS TO QUESTIONS *Q9.1 (a) No. Impulse, F∆t, depends on the force and the time for which it is applied. (b) No. Work depends on the force and on the distance over which it acts. *Q9.2 The momentum magnitude is proportional to the speed and the kinetic energy is proportional to the speed squared. (i) (ii) The speed of the constant-mass object becomes 4 times larger and the kinetic energy 16 times larger. Answer (a). The speed an...

Displacement - Answer Position of an object relative to its starting position. Velocity - Answer Rate of change of displacement. Speed - Answer Rate of change of distance. Acceleration - Answer Rate of change of velocity. Newton's First Law - Answer An object continues in uniform motion in a straight line/ at rest unless a resultant force acts. Newton's Second Law - Answer The acceleration of an object is proportional to and in the same direction as its res...
