You must answer the question below. It's only 2 question so please provide answer on it. 1. What are the different forms of energy? 2. What are the laws of energy transformation and cite examples? Thank you in advance.
What do you mean by work and energy?
what is the kinetic energy of a car that is traveling 10.9 m/s if it has a mass of 1,376 kg? sumbit you answer in exponential form.
What is energy? Explain why scientists care about this concept as part of their work.
What is power? Calculate the power to move a 9 J box in 20 seconds. Calculate the power used for a 500N student to run 3 m in 5 seconds. How much work is used when a 200-Watt machine runs for 30 seconds?
If it takes total work W to give an object a speed v and kinetic energy K, starting from rest, what will be the object’s speed (in terms of v) if we do twice as much work on it, again starting from rest? Round off your result to 1 decimal place.
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) 13. When you throw a ball, the work you do to accelerate it equals the kinetic energy the ball gains. If you do twice as much work when throwing the ball, does it go twice as fast? Explain.

Later, the same person walks up the same stairs and does not feel as tired. Why is this? Ignoring air resistance, does it take more work or energy to run up the stairs than to walk up?

During a brief period the track exerts a downward force on the cars. Describe what is happening. (What is the shape of the track at this point?)
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) If we know that a force of 5 N acts on an object while it moves 2 meters, can we calculate how much work was done with no other information? Explain.
