Multiply the object's velocity by itself in order to obtain the square of the velocity (velocity times velocity). Step 5 Multiply the value you calculated in Step 5 (mass) by the value you calculated in Step 4 (velocity). You now have the kinetic energy of the object. Cite This Article...
Step 3:Identify or calculate the work done on the object. Step 4:Identify or calculate the initial energy of the object. Step 5:Add the result fromStep 4with the result fromStep 3. Step 6:Using the result fromStep 5equate it to the equation of kinetic energy and...
Work can also be defined as the change in kinetic energy of the system since change in kinetic energy also implies energy transfer.Answer and Explanation: The work done is W=49 J To solve for the work, we can use the equation that relates force and work, which i...
Kinetic energy is the energy due to motion, and is given by KE= 0.5 m v^2, where m is mass and v is velocity. Now ask yourself, before the sphere is dropped, what is it's kinetic energy? Since it's velocity is 0, logically it has no kinetic energy. However, it has gravitat...
How fast a bullet is traveling when it leaves the end of a gun's barrel, called the muzzle velocity, is of great interest to both those who work in the field of ballistics and physics students looking to cover a few key concepts in one, well, shot. If the mass m and muzzle...
If it falls over the edge of the cliff, it starts to pick up velocity, i.e. gains kinetic energy (motion energy) while losing potential energy. When it hits the ground, this energy is dissipated as heat (think of the heat produced by an asteroid impact). Similarly when an appliance ...

(where I is the moment of inertia and ω is the angular velocity). "Moment of inertia" sounds horribly abstract and confusing, but it's much easier to understand than you might think. What it really means is that, from the viewpoint of kinetic energy and momentum, the effective mass of...
Thus if you know the mass of the object, you can use algebra to solve for the velocity v by setting _EP (initial) to EK_ at "launch." We can describe the total mechanical energy of such a situation as the sum of kinetic and potential energy. ...
and velocity v is the sum of kinetic energy _EK, which is found using the relationship mv_2/2, and gravitational potential energy EP, found using the product mgh where g is the acceleration owing to gravity and h is the vertical ...
