- 1Calculate the kinetic energy of each object is given below. Compare the kinetic energy you will obtain in (A)with that in (B); Compare the kinetic energy you will obtain in (C) with that in (D). a) A 1500kg car moving at 2 m/s b) A 1500 kg car moving at 20 m/s c) A 2000kg elephant moving at 2 m/s d) A 2kg puppy moving at 2m/sWhat is absolute zero? What is kinetic energy and potential energy? Give examples. You have a ball in your hand above the ground at rest which you then drop. What energy is involved in each part of this situation and how do we know that total mechanical energy has been conserved? Explain with and without air resistance present. A boulder and a pebble are sitting on a cliff, which has greater gravitational potential energy and why? A cheetah and a person are racing, both has the same mass, which has a greater kinetic energy and why? What is temperature? How does an objects temperature relate to motion of the molecules? What is heat? Describe thermal expansion/contraction. When temperature rises, which one occurs? I have a 2kg ball on a cliff 10m high. If the gravitational acceleration on this planet is 4m/s2, what is the GPE of the ball? A 2kg ball is rolled at 3m/s. What is the KE of the ball? What is work? And what are the units for work? How does this…
- Write at least one paragraph explaining what kinetic energy is and how mass and height affect the amount of kinetic energy in an object.what is the equation you use to calculate gravitational potential energy13. You learned in Science that Energy is conserved, that Potential Energy must balance Kinetic energy. Mathematically, that means: 1 mgh =-mv², where mgh is Potential %3D Energy 1 and -mv² is Kinetic energy. Reminder that m is 2 mass, g is the acceleration due to gravity, h is height and v is velocity. a) Balance this equation such that the sum of Potential and Kinetic Energy is zero (hint: gravity is negative). b) Solve this equation for v; again, you only need the Algebra you've learned! (hint: don't worry about the negative at the end!) Show your work! + tv MAR 18
- A car accelerates from 10 km/hr to 40 km/hr, how much does its kinetic energy change? a) KE doubles, b) KE quadruples, c) KE increases eightfold, d) KE is cut in half, or e) you would need to know the mass of the car to determine the change in KE.Write the kinetic, potential and total energy of a baseball having a mass of 0.145kg held 10 meters above the ground. The baseball was released under the influence of gravity on Earth and freefalls to the ground. Write the kinetic, potential and total energy of the baseball at the point the baseball hits the earth. What is the baseball’s final speed when it impacts the ground using the principles of Energy Conservation?please help.
