Work and Energy 1.Work Energy  Work done by a constant force (scalar product)  Work done by a varying force (scalar product & integrals) 2.Kinetic Energy.

Force: push or pull  all forces have size and direction  measured in Newtons (N) An object will speed up, slow down, or turn Only if something is pushing.

Work, energy, and power. If the net force is in the direction of motion work is positive If the net force is in the direction opposite that of motion.

Week 2 Pull

Pull If we don’t want to push things, we pull them. We need more force to do it compared to push

Pull Activity tug of war: set the class into 2 groups on each end of a rope. let them have fun and start a tug of war

Springs in figure 2, the spring is being stretched or extended extension - when we want to stretch things out, it is called an extension

Week 2 Vocabulary Pull: When you apply force in the opposite direction. Displacement: How much something has moved. Kinetic energy: The energy an object has due to its motion.
