Kinetic Energy and Work-Energy Theorem. In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the direction of displacement and perpendicular to the displacement which is called the normal force.
A: Kinetic energy is the form of an energy that object can possess because of motion of an object.… Q: Kinetic Energy depends on: O Weight and Height Speed and Mass O Speed and Direction A: The kinetic energy is given by KE=12mv2

(a) Find the kinetic energy of a 78.0-kg spacecraft launched out of the solar system with speed 106 km/s by using the classical equation K = 1/2 mu 2. (b) What If? Calculate its kinetic energy using the relativistic equation. (c) Explain the result of comparing the answers of parts (a) and (b).
Since the initial potential energy and final kinetic energy are zero, our equation now becomes EP,f = EK,i. We can then substitute the formula for kinetic energy, EK = 1/2mv2, and the formula for gravitational potential energy, EP = mgh, mghf = 1/2mvi2.
Consider the kinetic energy equation, mv² where m is the mass and vis the veloc- ity. If two gases have the same kinetic energy, KE, but one has a larger mass, what does that mean for the velocity of that gas, or diffusion rate? A The velocity decreases as the mass increases. B U The velocity is negative.

1. Assuming that there are no heat effects and no frictional effects,find the kinetic energy and speed of a 3220lb body after it falls 778 ft from rest. Start with the steady flow equation, deleting energy terms which are irrelevant. Draw a figure or FBD that will support the problem. Explain each step by step formula.
