Activity 3-1: Kinetic Energy In this activity you will explore the meaning of kinetic energy, and see how it is calculated. 1. Toss one book up in the air and catch it. If you throw it faster it will go higher. Alternate between fast tosses and slow tosses. Notice how much effort it takes to throw it and to catch (stop) it when it is moving quickly or slowly. Question 3-1: Does the effort needed to stop the book seem to change as its speed increases? How does it change? Explain. Question 3-2: Does the effort needed to throw the book seem to change as its speed increases? How does it change? Explain. 2. Now toss the two books together (some rubber bands will help in having them stay together). Compare tosses of one and two books that go up at the same speed. Again notice how much effort it takes to toss and stop the book(s). Question 3-3: Does the effort needed to stop the two books seem to change as the mass increases compared to a single book? How does it change? Explain. Question 3-4: Does the effort needed to throw the two books seem to change as the mass increases compared to a single book? How does it change? Explain.

Suppose you lift a 25 kg box by a height of 1.0 m. How much work do you do in lifting the box? Instead of lifting the box straight up, suppose you push it up a 1.0 m high ramp that makes a 30 degree angle with the horizontal, as shown in (Figure 1). Being clever, you choose a ramp with no friction. How much force is required to push the box straight up the slope at a constant speed? How long is the ramp? Use your force and distance results to calculate the work you do in pushing the box up the ramp.
I am extremly confused on this please help me.
Energy is conserved??!! What?? A ball moving has kinetic energy but itwill NOT stay moving forever…. Where did the energy go? List all thedifferent ways energy can manifest itself. If this list doesn’t include ATLEAST 5 different ways then use your time to research different waysenergy can manifest itself… I’ll give 3 that you should be able to defineeasily. 1. Gravitational Potential Energy 2. Kinetic energy 3. SpringEnergy. Please define these and all the different ways energy manifests.
