Kinetic energy of a moving object = mass times 1/2 (speed of the object)2
Energy of a photon = mass times 1/2 (speed of light)2
Energy from converting mass to energy = mass times (speed of light)2
Why the difference ? ? ?

So 2 x kinetic energy = mass x velocity squared
Momentum = mass x velocity

What would be the effect on the orbital velocity of satellite if mass of satellite is double?
Its mass won't affect the orbital velocity.
How does the gravity of the planet vary with their mass?
Force of gravity equals mass of planet times mass of other times the constant (G) that makes the units work all divided by the distance from one to the other AND the other to one (turns out to be distance squared). F=GxM1xM2/(DxD)
How does weight change as you move away from or towards the center of gravity?
Weight is technically the force that gravity exerts on you. Mass is how much matter you "are". Mass times the acceleration of gravity will equal your weight. Newton discovered that the force of gravity [your weight] is equal to a constant times the mass of the planet times the mass of you all divided by the radius to the center squared. This equation shows that the weight is inversely proportional to the radius to the center squared. Thus, as the radius to the center increases, the weight will decrease. So if you move away, your weight will decrease.
The momentum of an object depends on what two forces?
The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
What is the tangential velocity and centripetal acceleration of the earth moving around the sun?
Tangential velocity squared is GMs/r and velocity v =29814m/s and the centripetal acceleration is v2/r= 5.928 E-3 m/s2
How fast is a 4kg bird flying if it has 8 joules of kinetic energy?
Use the formula KE = 1/2 mv2 (kinetic energy = 1/2 times mass times velocity squared).Use the formula KE = 1/2 mv2 (kinetic energy = 1/2 times mass times velocity squared).Use the formula KE = 1/2 mv2 (kinetic energy = 1/2 times mass times velocity squared).Use the formula KE = 1/2 mv2 (kinetic energy = 1/2 times mass times velocity squared).
How is kinetic energy defined?
It is equal to one half of the mass times the velocity squared
How do you calculate mass when given joules and velocity?
Kinetic energy = (1/2) (mass) (velocity squared)Divide each sideby (velocity squared/2): Mass in kg = ( 2 x energy in joules) / (velocity in m/s) squared
If you double the speed of a car you increase its force of impact by how many times?
four times as great
What is the mass of an object multiplied by its velocity?
The product of mass and velocity of an object is its momentum.
How do the mass and speed of an object affect the energy?
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
How do the mass and speed of an objects affect the kinetic energy?
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
How do the mass and speed of and object affect the kinetic energy?
Kinetic energy is the mass times one half the velocity squared. KE = ½mv².
What is the formula to calculate kinetic energy?
Kenetic energy equals one half mass times velocity squared.
The amount of kinetic energy an object has depends upon what factors?
Kinetic energy equals 1/2 mass times the velocity squared, so mass and velocity (speed)
Why mass is variable in E mc 2?
It is not a variable. The equation says that the energy contained in any given mass is equivalent to the mass times the velocity of light squared.
What form of energy does a cross bolt hitting a target?
Kinetic energy equal to half the mass times the velocity-squared.
