![]() ![]() ![]() ![]() more than one force acts, the total work done is the work done the net force. If work is energy is transferred to the system, if work is energy is transferred out of the system. as the dot product W F (dot products are just the magnitude of the two vectors times the cosine of the angle between the vectors, W work is done if the force applied does not produce a displacement the force applied is perpendicular to the displacement, no work is done as cos90 0 is energy transfer. Work the amount of energy that is transferred to an object or system the action of a force on that system through some distance. D A v2 2m 2 2 mg 2mg so v this gives the terminal velocity vT DA DA Energy. 1 2 D A v 2 So the terminal speed is reached when the net force is zero (zero acceleration). Downwards vertical motion of a falling object. density of air ( A the area pushing against the fluid Eg. higher speeds (turbulent conditions) R where D drag coefficient (dimensionless), usually about 0 for spherical objects. This equation works for laminar flow and slow speeds. R b is a proportionality constant, while the negative sign represents the direction is in the opposite to that of the motion. forces depend on the speed of the object. Direction is always opposite to the direction of motion (relative to the medium). For motion through a fluid, the medium will exert a resistive force (drag), R on the object moving through the medium. ONLY if the object is on the verge of slipping this becomes F s friction acts when the object is motion Fk Resistive forces. friction acts to keep the object from moving, Fs ( n is the normal force). Friction is a force that always opposes the direction of motion and is parallel to the surfaces in contact. #Physics 101 mechanics pdf free#Law F ma (can also be expressed in terms of components, Law The action force is equal and opposite in direction to the reaction force Free body diagrams Inclined planes Forces of friction (two static and kinetic). Law no net force (net force when moving at a constant velocity. Preview text Phys 101 Mechanics summary: WEEK 1: Kinematics and Laws.
