Chapter 6

Chapter 6. Work, Energy, Power. Work. The work done by force is defined as the product of that force times the parallel distance over which it acts. The unit of work is the newton-meter, called a joule (J) Work is a scalar. q. Work. s cos q. q. Work. F cos q. Energy.

Work and Energy

Work Done by a Constant Force. Work is the product of the displacement and the force component in the direction of the displacement:W = F cosq d (a scalar)Where the units of work are the Joule, J,1 J = 1 N m. Example of a constant force work calculation.. F = 250 N at 300 below hori

Work

Work. Mechanical work. Applying a force on an object that displaces the object in the direction of the force. W = F Δ d Only when the magnitude of the force is constant. Scalar (no direction associated with work) SI unit: N•m When force and displacement are in the same direction!. N•m.

Work, Energy, and Power

Work, Energy, and Power. Work Work tells us how much a force or combination of forces changes the energy of a system. Work is the bridge between force (a vector) and energy (a scalar). W = F ∆r cos θ F: force (N) ∆ r : displacement (m) θ : angle between force and displacement. Work

Work and Machines

Work and Machines. Chapter 5 Section 1. What is work ?. Work is the transfer of energy that occurs when a force makes an object move. The amount of work is dependent on. a. the force exerted b. the distance over which the force is applied Work = Force X distance.

Work & Energy

Work & Energy. WORK. WORK : It is used by physicists to measure something that is accomplished. So it results in the equation: Work = Force x displacement The symbol for work is the variable = W W=(F)(d) You must move something (d) with a force (F) to accomplish work.

Work

Work. Work happens when a force causes an object to move through a displacement . Be careful with this definition. Some people incorrectly assume that it means a force is work. Instead , what it really means is that a force exerted on an object can cause work to happen.
