10.2 - Work and energy transformations
So far, we have considered the energy in a system before and after a change. However, energy can alsoenter or leave a system. Mechanical energy enters or leaves a system through work, the action of forces.Work done on a system increases the system's total energy. Work done by a system decreases thesystem's total energy. This section broadens the scope of conservation of energy to include work done onor by a system.
Work and energy
How doforces
change theenergy of a
system?
Recall that work is a form of energy. The work done by a force is the force multiplied by thedistance moved in the direction of the force. Consider a system containing an uncompressedspring at its free length. A force acts from outside the system to compress the spring adistance, x. The final energy of the system is the initial energy it started with plus the workdone on the system by the external force.
What if thesystem does
work?
Again, consider the system to consist only of the spring. If the spring is now used to launcha ball, the system does work on something outside the system: the ball. When a systemexerts a force that does work outside the system, then the final energy is the initial energyminus the work done by the system.
Work andconservation
of energy
If all forces act inside the system, then the total energy of the system remains constantbecause all the energy lost by one part of the system is gained by another part. If forces actoutside the system, then the energy of the system either increases when work is done on thesystem or decreases when the system does work on the outside environment.

Objective 1: A racecar is moving with a speed of 200 km/h on a circular section of a racetrack that has a radius of 300 m. The racecar and the driver have a mass of 800 kg. (in slide presentation)
a) What is the magnitude of the centripetal acceleration felt by the driver? answer: 10.3 m/s2 (1.0 g)
Objective 2: A racecar is moving with a speed of 200 km/h on a circular section of a racetrack that has a radius of 300 m. The racecar and the driver have a mass of 800 kg.
b) What is the centripetal force acting on the car? answer: 8240 N
Objective 3: In the case of a car rounding a turn as shown, what physical force is acting radially to keep the car moving in a circular path?
answer: Static friction between the tires and the road provides the centripetal force.
Prior knowledge
This lesson introduces centripetal force and centripetal acceleration. Students should be familiar with Newton’s 1st and 2nd laws of motion and with the variables used to describe circular motion.

Teach as if you spent days prepping each lesson.
Centripetal force Content The lesson begins by defining centripetal force. Students explore the relationships
between velocity, centripetal acceleration, and centripetal force for objects in circular motion through a guided inquiry activity, using an interactive simulation. The quantitative relationships between these variables are presented and connected to Newton’s second law. The four-step problem solving method is demonstrated and applied to solve circular motion problems.
Learning objectives
The student will be able to: 1) describe and analyze the motion of objects moving in circular motion; 2) apply Newton’s second law to circular motion problems; and 3) interpret free-body force diagrams.
Materials/ technology resources
1) Demonstration: yo-yo or any small object on a string 2) Slide presentation: “CentripetalForce.ppt” 3) Interactive simulation: “Circular motion” 4) Interactive calculators: “Centripetal acceleration” and “Centripetal force” 5) Student work: “CentripetalForce.pdf”
Lesson plan segments
• Demonstration: Swing the yo-yo in a circle at constant speed and ask the students if it is accelerating. Lead them to see that the velocity vector is changing (in direction, though not in magnitude), and that circular motion is the strange case of acceleration at constant speed.
• Slide presentation: The presentation defines centripetal force and provides a guided inquiry into the relationships between velocity, centripetal acceleration, and centripetal force using an interactive simulation. These relationships are then formalized using Newton’s second law of motion. The presentation distinguishes between centripetal and centrifugal forces, poses problems related to circular motion, and demonstrates the application of the four-step problem solving method.
• Investigation: In part 1 of the investigation students examine the direction of velocity, acceleration and force vectors. In part 2 they model a mass swung overhead. In part 3 they graph the proportional relationship between the radius and velocity for an object with constant acceleration.
• Student work: Centripetal force assignment Students should work in pairs to complete the assignment while using the interactive simulation. Bring the class together for a discussion of the relationships depicted in the two graphs in part three.
• Reading: from the Essential Physics textbook
Centripetal force
Investigation 7A: Circular Motion Part 1: Directions of the velocity, force and acceleration vectors
1. Set m = 5.0 kg, r = 5.0 m, and v = 5.0 m/s. 2. Play the simulation and then pause it at various positions around the circle. 3. On the circle below, sketch the velocity, force and acceleration vectors for at least five
positions around the circle. Questions:
a. Which vector quantity or quantities are radial and which are tangential? Are the radial ones pointed inwards (towards the center) or outwards?
b. Do the lengths of the velocity, acceleration or force vectors change as the object moves around the circle?

Learn physicsby doing physics
Simulations allow students to try things that are impossible or impractical in the lab. More importantly, each “experiment” takes only seconds. Students learn by exploring many variations that they control. This exploration builds deep understanding of physics relationships in a way that is impossible with traditional books and labs.
Interactive simulationsunlock new modes of learning
We designed the next generation of physics lab apparatus to be rugged and reliable as well as
provide unparalleled accuracy. Our state-of-the-art technology is completely coordinated with the
curriculum! Every experiment works as written because we
designed the curriculum and the equipment to work together.

“This is a great interactive way for students to learn physics. It allows for so many iterations of actually manipulating different variables. I think the instant feedback will allow students to constantly stay engaged in what they are learning.”
“The new Essential Physics program is excellent. Technology and interactive programs help students visualize physics. The real world examples show students how science is used in their everyday lives, including home and in the workplace. It has material for regular, pre AP and AP physics B incorporated into the book. This will be helpful for all of my classes.”

What teachers are sayingabout Essential Physics
“We have been teaching and creating exceptional science curriculum for 25 years. We have all heard, repeatedly, how technology was going to revolutionize learning. But computers were not reliable enough. Software changed too often. Somehow, the revolution never quite happened. It is happening now. Essential Physics puts the power of technology into your hands, reliably, and with the tools you need to be successful in today’s diverse classrooms.”
