Course Title : Physics & Laser Course Code : BAS 111 Department : Physics Lecture 1 Forces and Momentum Dr. Yasser Abdou Physics Department @ Alsalam University [email protected] Quiz ▪ What is the acceleration produced by a force of 15 N exerted on an object of mass 3 kg? ▪ What force accelerates a 50 kg mass at 5 ms–2? ▪ The object momentum is changed from 10 to 5 kg m/s in 2 seconds. What is the force? ▪ Why do we fall forward, when a moving bus stops suddenly? ▪ Two similar trucks are moving on a road with the same velocity. One of them is empty while the other one is loaded. Which of the two has more momentum? Activity Newton's third law states that every action has an equal and opposite reaction. Explain how this principle also applies to moving teeth. Thank you
