In terms of ordered derivatives:. 5 m/s/s. What is the mass of the crate?. With what force must you hit a 5-kg baseball to get an acceleration. 175 m/s/s?. You and your bicycle have a mass of 75-kg. If your pedals put a forward force of 190 N, and friction pushes you backwards with a force of 20 N. Air resistance also pushes you backwards with 10 N. . Free body diagrams . show the magnitude and direction of ALL of the forces acting on an object. . Generally we represent the object as a box with the force arrows coming out from the centre, in the direction they are acting.. TAKS Objective Four. TAKS Objective 4. – The student will demonstrate an understanding of motion, forces, and energy.. TEKS 8.7. The student knows that there is a relationship between force and motion.

Students will be able to:. . Scalars and vectors. . Types of forces. . Resultant of forces. . Equilibrium of particles. Scalar and Vectors. . Scalar - . a physical quantity that is completely described by a real number. A truss is a structure composed of slender members joined together at their end points. The members commonly used in construction consist of wooden struts or metal bars.. Assumptions for Design.. To design both the members and the connections of a truss, it is necessary first to determine the force developed in each member when the truss is subjected to a given. A particle is said to be in . equilibrium . if it remains at rest if originally at rest. , or . has a constant velocity if originally in motion. .. To maintain equilibrium, it is . necessary . to satisfy. 4 - . 2. Equilibrium of a Rigid Body in Three Dimensions. Six scalar equations are required to express the conditions for the equilibrium of a rigid body in the general three dimensional case..  .
