Calculate the initial potential energy (PE = mgh). Assume that all of this gets converted to kinetic energy, and solve for velocity (KE = 0.5 mv2).

Does potentail energy have an influence on the final velocity of a falling object?
yes it does. u can calculate the final velocity of the falling object with the following eqn: initial potential energy= final kinetic energy or mgh = 1/2mv2 where m=mass, h = height,v=final velocity
What kind of energy is in a falling object?
Kinetic energy of a falling object can be calculated for a specific height at a specific point since a falling body accelerates which means that it's velocity is changing every moment. To calculate the kinetic energy of a falling body at a certain height, we should know the mass of the body and its velocity at that point.Then we can apply the following formula: K.E. of an object = 1/2(mv2)
Which is the correct equation for kinetic energy?
Kinetic Energy = (1/2) x (Mass) x (Velocity)2
How do you find change in velocity?
when using energy use the kinetic energy equation for change KE = .5(M)(Vf^2 - Vo^2) M = mass Vf = fianal velocity Vo = initial velocity
The equation for kinetic energy is .?
KE=1/2mv2Kinetic Energy = 1/2 (mass X final velocity)2
Where velocity is squared in the kinetic energy equation doubling an object's velocity will do what to its kinetic energy?
Multiply it by 4 (4 = 22)

Without using time as a variable in the equation how can you calculate the velocity of a ball when it hits the floor?
You can use energy if you have the height from where the ball is released. (This is assuming the ball is falling straight down). Potential Energy (PE)=Kinetic Energy (KE) because energy is conserved. mgh=1/2mv2
How do you find the kinetic energy of a falling nickel?
1) measure its mass and velocity. 2) Measure where its falling from. (the kinetic energy will equal the potential energy up to the instant the nickel stops).
Why can an object have kinetic energy and potential energy?
Because they are not mutually exclusive. Take for example a falling object; while falling at a given velocity it has (.5)(mass)(velocity)2=Kinetic Energy but also has the potential energy of whatever distance it has yet to fall, which equals (mass)(gravity)(height)=Potential Energy These two types of energy equal the Total Energy of the falling object, which never changes as it falls.

What are the two parts of kinetic energy?
The non-relativistic equation for kinetic energy is mv^2/2 where mass is m and velocity is v. The relativistic kinetic energy equation is m/(1-(v^2/c^2))-m where m is mass, v is velocity and c is the speed of light. The two variables which determine the kinetic energy of an object are mass and velocity.

What is the equation that shows the quivalency of mass and energy?
E=MC2Where:E= energyM= massC= the velocity of light.
How does movement use energy?
Movement itself does not use energy. However if there is friction then energy will be lost according to the equation, Work = Force x Distance. Also, there is energy associated with movement according to the equation, Ek=½mass x (velocity)²
