Premium member Presentation Transcript Forces : Forces Dynamics : Dynamics Study of the effects of forces on matter Four Fundamental Forces : Four Fundamental Forces Gravitational-force of attraction that exists between all masses Electromagnetic-forces between charge particles Strong Nuclear Force-holds the nucleus of an atom together Weak Nuclear Force-mainly within particles inside the nucleus Newton’s First Law : Newton’s First Law An object in motion stays in motion, an object at rest stays at rest unless an outward force acts on it. Inertia is the tendency for an object to remain in the same state of motion Newton’s Second Law : Newton’s Second Law States that when an unbalanced force acts on an object, the object will accelerated in accordance with equation F=ma Newton : Newton One newton (N) is the force necessary to accelerate a 1 kg mass at the rate of 1 m/s2 Mass : Mass Is a measure of the inertia of a body Weight is a measure of the gravitational force on a body Mass : Mass Gravitational mass and inertial mass are two essentially different concepts. However, the gravitational and inertial masses of a body are numerically equal Friction : Friction Force that opposes the motion of two objects in contact Force of friction : Force of friction Is equal to the product of the coefficient of friction and the normal force Net force : Net force Is the unbalanced force acting on a body Freely falling body : Freely falling body Reaches terminal velocity when the upward force of the air molecules is equivalent to the body’s weight Newton’s Third Law : Newton’s Third Law States that every force is accompanied by an equal but opposite force. Formulas Needed : Formulas Needed F=ma F=force (N), m=mass (kg) a=acceleration (m/s2) W=mg W-weight (N), m=mass (kg) g=gravity (9.8 m/s2) Ff=muFn _ Ff- frictional force (N), mu -coefficient of friction (No unit), Fn -normal force (N) You do not have the permission to view this presentation.
