PPT-Forces and Newton’s Laws of Motion

The most important chapter of physics EVAR What is a Force A force is a push or a pull Contact forces Boat pulling a water skier Pushing a car with a dead battery Noncontact forces Gravitational attraction of moon to earth. Chapter 2 Section 2 Review. A. . An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.. B. . Every action has an equal and opposite reaction. . Forces act on you all the time. . If . you surf, you can feel many forces pushing and pulling you in different directions. . Gravity . always pulls you down, towards planet Earth. . This . force can be balanced by the support of the surfboard acting upwards. . Simple version of Newton’s three laws of motion. Newton’s Laws and the Mousetrap Racecar. 3. rd. Law: “for every action there is an equal and opposite reaction”. Is more mass a good thing or a bad thing for a mousetrap racecar to go far?. Housekeeping. Newton’s . First Law of . Motion. Newton’s Second Law of . Motion. Newton’s Third Law of Motion. Glossary. Inertia. is the property of objects that makes them resist changes in their motion. So, the greater the mass of an object, the more inertia it has. For example, it takes a much . Forces. Forces can be thought of as pushes and pulls. Examples. You exert a force on a door to open it (a push). Gravity exerts a force on you which holds you to the surface of the earth (a pull). Forces.

It is a universal force that causes all objects to pull on all other objects everywhere. Forces and Uniform Circular Motion Physics Unit 2 This Slideshow was developed to accompany the textbook OpenStax Physics Available for free at https:// openstaxcollege.org/textbooks/college-physics Dynamics I Forces & Newton’s First Law 4 Natural Forces Gravity : acts between all masses in the universe and has “infinite” range Electromagnetic (EM) Force : acts between electrically charged particles and “magnetically charged” poles Forces and Newton’s Laws SP1. Students will analyze the relationships between force, mass, gravity, and the motion of objects. d. Measure and calculate the magnitude of frictional forces and Newton’s three Laws of Motion.
