Vector graphics is the use of geometrical primitives such as points‚ lines‚ curves‚ and shapes or polygon(s)‚ which are all based on mathematical expressions‚ to represent images in computer graphics. "Vector"‚ in this context‚ implies more than a straight line. Vector graphics are based on images made up of vectors (also called paths‚ or strokes) which lead through locations called control points. Each of these points has a definite position on the x and y axes of the work plan. Each point‚ as

A force is required in uniform circular motion.Centripetal Force & AccelerationSince an object in motion will travel in a straight line (Newton ’s First Law) an force must be required to accelerate the mass . This force does not cause a change in velocity as stated in the introduction‚ but rather it is responsible for the change in direction. The

Definition of Force A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects‚ there is a force upon each of the objects. When the interaction ceases‚ the two objects no longer experience the force. Forces onlyexist as a result of an interaction. Velocity‚ Acceleration‚ Momentum‚ and Impulse Velocity‚ in physics‚ is a vector quantity (it has both magnitude and direction)‚ and is the time rate of

Centripetal force (from Latin centrum "center" and petere "to seek"[1]) is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body‚ toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion. In simple terms‚ centripetal force is defined as a force which keeps a body moving with a uniform speed along a circular path and is directed along the radius towards the centre

Centrifugal force Centrifugal force (from Latin centrum‚ meaning "center"‚ and fugere‚ meaning "to flee") is the apparent outward force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body as the body’s path is continually redirected. In Newtonian mechanics‚ the term centrifugal force is used to refer to one of two distinct concepts: an inertial force (also called a "fictitious" force) observed in a non-inertial reference frame‚ and a reaction force corresponding

transcontinental plane flight‚ your coffee cup sits motionless on your tray. Are there forces acting on the cup? If so‚ how do they differ from the forces that would be acting on the cup if it sat on your kitchen table at home? Determine the Concept Yes‚ there are forces acting on it. They are the normal force of the table and the gravitational pull of Earth (weight). Because the cup is not accelerating relative to the ground‚ the forces are the same as those that would act on it if it was sitting on your table
