PPT-FORCE and Newton’s Laws of Motion

Definitions of Force Force is a push or a pull acting on an object Force is a vector magnitude amp direction Force can be contact or long range aka noncontact or field. 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. . Motion. Newton’s first law of motion states that an object will remain at rest or moving at a constant velocity unless it is acted upon by an unbalanced force.. An unbalanced force will cause an object to speed up, slow down, or change direction.. 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?. Adam Grigsby and Harrison McCroskey. 3. rd. Block. 10/3/14. Newton’s First Law of Motion. An object in motion will stay in motion and an object at rest will stay at rest unless acted on by an unbalanced force. . Robert Strawn. Compiled 10/16/11. A force is any push or pull that one object exerts on . another that causes a change in motion, direction, or shape.. The unit for force is the Newton (N) and is equal to . fig_03_022. Nicolaus Copernicus. Copernicus’ Universe. Contrast Copernicus with the Aristotelian Cosmos. GALILEO. Galileo Galilei 1564 - 1642. Galileo's most original contributions to science were in mechanics: he helped clarify concepts of acceleration,. 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. 1. st. Law of Motion. Inertia. An object will remain at rest or in constant motion unless acted upon by an unbalanced force. . “The Old Tablecloth Trick”. How does this comic relate to Inertia? . 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. Changes in Motion. Objectives:. 1. Describe how force affects the motion of an object.. 2. Interpret and construct free-body diagrams.. The Force is Strong With You. Force. is an action exerted on an object which may change the object's state of rest or motion.. Forces. We have learned that forces . either pushes or pulls.. They come in many varieties:. Gravity & Normal. Kinetic & Static Friction. Electrical & Magnetic. Air resistance. Tension. Nuclear Force. Relative motion. Projectile motion. Newton's laws of motion. Questions?. Sessions setup. Mondays: Review and preview with PowerPoint outline. Tuesdays: Worksheets and open for in-session questions. Wednesdays: Worksheets and open for in-session questions. Acceleration, Force, and Newton’s Laws Demonstration Watch what happens when I bounce a tennis ball on the desk. What happens to its position? Direction? What happens to its speed? What happens to its velocity?
