What is the kinetic energy of a 44 kg cheetah running at 31 m s?
Answer: 21,142 J is the answer.
Which car has the most kinetic energy?
Answer: The first car has the most kinetic energy.
What is the greatest kinetic energy?
When these objects move at the same speed, which will have more kinetic energy? The semi- truck has more mass; therefore, more kinetic energy! An object has the MOST kinetic energy when it’s movement is the GREATEST.
What are two kinetic examples?
Examples of Kinetic Energy A truck travelling down the road has more kinetic energy than a car travelling at the same speed because the truck’s mass is much more than the car’s. A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass.
Which block has more kinetic energy?
Remember the Work-Energy Theorem. The work done on the blocks will be the kinetic energy. Well, since Block 1 has less mass and is experiencing the same amount of force, it will travel a greater distance than Block 2 as the spring is pushing on them. Since W = Favg×d, the smaller block will have more kinetic energy.
At what position does the ball have the most kinetic energy?
When the ball is held at its highest point, it has potential energy, specifically gravitational potential energy. 2. When the ball is falling towards the table, it has kinetic energy. It has the most kinetic energy at the very end of its descent when it is moving the fastest.
What are the four assumptions for an ideal gas?
For a gas to be “ideal” there are four governing assumptions:
- The gas particles have negligible volume.
- The gas particles are equally sized and do not have intermolecular forces (attraction or repulsion) with other gas particles.
- The gas particles move randomly in agreement with Newton’s Laws of Motion.
What are the 3 parts of the kinetic theory?
Terms in this set (3)
- Part 1 kinetic theory. All matter is made up of tiny particles.
- Part 2 kinetic theory. These particles are always in motion.
- Part 3 kinetic theory. Particles with more mass move more slowly then particles with less mass.
What is the relation between kinetic energy and temperature?
Temperature is directly proportional to the average translational kinetic energy of molecules in an ideal gas.
What does average kinetic energy depend on?
temperature
