Is kinetic energy of a body in motion equals the product of half its acceleration?

No. Kinetic energy is 1/2 times mass times velocity squared - so as you can see, acceleration doesn't even enter the equation. If it accelerates, the speed will change, though, and so will its kinetic energy.

Kinetic energy divided by potential energy equals?
1
What is the equation for mechanical power?
It's:P= Fd/t
What is the mass of an object multiplied by its velocity?
The product of mass and velocity of an object is its momentum.
Can energy to be both potential energy and kinetic energy?
Yes but not both at the same time. All energy is conserved, therefore energy before equals energy after. For example jumping from a ten metre diving board you have gravitational potential energy as you are fulling gravitational potential energy is converted to kinetic energy.
What is the difference in stopping time between 60mph and 30mph?
The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.
What energy occur as a pendulum swings?
There is Mechanical Energy. This Mechanical Energy equals Potential + Kinetic Energies. At the maximum heigh and with the pendulum set still there is the maximum Potential Energy (so Kinetic equals 0, and Potential Energy equals Mechanical Energy). When we release the pendulum this Potential Energy transforms into Kinetic Energy which will be maximum and equal to the Mechanical Energy when the 'rope' or 'string' that holds the pendulum is in the same direction as the acceleration, or force, in this case gravity. Then, and if there is no friction (e.g. air) the pendulum will reach the same maximum heigh that it had in X0 and the Kinetic Energy will transform into Potential, reinitiating the process but in the opposite direction. Hope i helped and sorry for my english. :)
When you throw a ball into the air its kinetic energy equals?
is converted to potential energy as it goes higher.
What is kinetic energy plus potential?
It equals basic energy
Kinetic energy divided by potential energy equals?
1
What will happen to the kinetic energy of a body if m equals 2m?
Kinetic energy = 1/2 (mv)2 if m increase by 2m, then Kinetic increases by 2
What is the equation for mechanical power?
It's:P= Fd/t
Potential energy plus kinetic energy equal what?
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
How are mass and acceleration related?
Newton's Second Law: force = mass x acceleration
Derivative of kinetic energy?
Kinetic energy is a measure of energy and is therefore measured in joules (J). In S.I. units, a J can be written in its most basic form as: (kg m^2)/(s^2) This is apparent from the kinetic energy equation: KE = (1/2) m v^2
Should a large truck and a small car moving at the same speed have the same kinetic energy?
No. The large truck has more kinetic energy than the car. Mass is a variable in the equation for determining kinetic energy. Kinetic energy equals 1/2 the mass of the object time the speed (really 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)
What is the mass of an object multiplied by its velocity?
The product of mass and velocity of an object is its momentum.
