If a ball falls in vacuum from a certain height describe the total energy, the kinetic energy, and the potential energy during the fall. Describe the energy values at the initial point (highest point), at an intermediate point during the fall, and at the final point (ground level). Make sure to mention how the free fall in vacuum is different from a real life fall.

1.What is the unit for kinetic energy? 2.A collision in which kinetic energy is conserved is called what? 3. It takes no work to hold a cheerleader in the air, as shown here. If no work is done by the cheerleaders, why do they eventually tire? A.The concept of work, as it apples in physics, does not apply to any process that involves people. B.Their bodies expend chemical energy as their muscles function; this is "hard work," but not the...

Answer the following questions: 1. An object with mass M and velocity V has kinetic energy K= 1/2MV^2. If the velocity of the object is reduced to 1/5V, then its new kinetic energy is: a)1/5K b) 5K c)1/25K d) 25K 2. Velocity is a vector, therefore it has magnitude and direction. In a circular motion, the change in magnitude and direction of velocity respectively produce: a) centripetal acceleration and tangential acceleration b) tangential acceleration and centripetal acceleration c) tangential force...

2. Describe Kinetic Energy and Potential Energy. Describe the Law on Conservation of Mechanical Energy. If an object that is thrown perpendicular to the ground by neglecting the friction is required to go up to 125 m height, what should be the initial velocity of the object? Take the acceleration of gravity 10 m / s and assume that the mass of the object does not change.

1) can an object bothbhave kinetic energy and gravitational energy at the same time? Explain. 2)if an object has 6J of gravitational energy, in what process can it do 6J of work? 3) if a spring has 6J of elastic energy, in what process can it do 6J of work? Please help me answer the previous questions( I will give a good rating) thank you!
