  1. Introduction to Physics I For Biologists, Geoscientists, & Pharmaceutical Scientists

  2. Newton’s First Law • An object at rest remains at rest unless acted on by and external force. • An object in motion continues to travel with constant velocity unless acted on by an external force. • This is also known as the ‘Law of Inertia’.

  3. Newton’s Second Law • The force acting on an object is equal to its acceleration times its mass. • Mathematically: • Furthermore: • , where is the momentum.

  4. Newton’s Third Law • When two objects A and B interact, the force exerted by B on A is equal in magnitude and opposite in direction to the force exerted by A on B. • Mathematically:
