What is the equation used to compute the velocity of a falling object using energy?
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).
Which is the best term to use when describing the energy of motion?
The energy that comes from an object's motion is called kinetic energy. The object's kinetic energy can be found by using the equation K=1/2mv2 which means that kinetic energy is equal to one-half of the object's mass multiplied by the square of its speed.
Can kinetic energy be measured?
Kinetic energy can be measured, but the act of measuring it changes the kinetic energy of the object you are measuring. For example, you can measure the kinetic energy of a bullet fired from a gun by allowing the bullet to strike an known object and then measure the deflection/deformation of the target object. While it is possible to measure the kinetic energy of the bullet this way, the bullet itself is no longer moving after this measurement, and therefore your measurement caused a change in the bullet's kinetic energy. . Kinetic energy (E) can be calculated without changing the kinetic energy of the object under observation if you know the mass (m) of the object and if you can observe or calculate its velocity (v) using the equation E=(1/2)m/v2.
What is kinetic energy measured with?
Kinetic energy is calculated using mass and velocity. KE=1/2mv2
If an object's mechanical energy is equal to its potential energy how much kinetic energy does it have?
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.

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
Is swimming a kinetic energy?
yes,it is a kinetic energy,you are moving hence using energy
How do you calculate velocity using kinetic energy?
KE= 0.5mv2 so we have KE=50 m=50 v=1.414m/s

How do you calculate the minimum initial velocity for a rocket to reach the Moon using the gravitational potential energy equation?
Once you have the gravitational potential energy required to move an object a certain distance away from the Earth, you simply plug it into the formula for the kinetic energy, and solve for speed.
If chemical energy can be used to produce kinetic energy what is an example of using chemical energy to produce kinetic energy?
Your car.

How do you use kinetic in a sentence?
Joe was using kinetic energy when he was playing baseball.
What are the uses of kinetic and potential energy?
Anything that moves is using kinetic energy, so I'll let you answer that one yourself. Potential energy is a bit more abstract, so here's some of it's uses: - Batteries (electric potential energy) - Mass (potential energy in relativistic 4-space, hence E = m*c2) - The Schrödinger equation and Hamiltonian operator in quantum mechanics (the Hamiltonian is Kinetic Energy + Potential Energy = Total Energy, used to derive the time-dependent Schrödinger equation). - Enthalpy and the laws of thermodynamics.
