Honors Physics Midterm Questions with Certified Answers What is the difference between speed and velocity? Speed is the measure of how fast an object is moving, while velocity includes both the speed and the direction of the object's motion. How does Newton's Third Law of Motion apply to interactions between two objects? Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction, meaning that when one object exerts a force on a second obj...

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...
