This would require the knowledge of possible variables. Is body being displaced in terms of y? Is the body a projectile, shot by a spring? If the body is simply being pushed then the form of energy being shown would be Kinetic Energy (1/2mv^2).

A net force causes an object to?
Accelerate, motion is generated by applying force to mass.
What causes the current to decrease as an induction motor accelerates?
Because power is needed to accelerate the rotor and thus increase its kinetic energy.
What must a magnet do to generate an alternating current?
To generate an alternating current, a magnet must use kinetic energy. This means that the magnet must move at a certain speed and velocity in order to create a strong enough energy charge.
Does kinetic energy increase with speed and time?
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
How do you compare the units of work and kinetic energy?
Work and kinetic energy are defined as scalar energy and have the same units joules. dW=F.dr = (dP/dt) dr=dP(dr/dt) = dPv = vdP= mvdv W = F.r = mv^2/2. Physics has defined scalar energy but has no definition for vector energy mcV. Torque which is T= Fxr should be recognized as vector energy but it is defined as "Torque". This is another example of Physics not appreciating that the Universe is made of Quaternions, a Scalar part and a Vector part. E= FR = -F.R + FxR where the scalar energy has been defined as work (F.R) and the vector energy is defined as Torque FxR. Kinetic energy is a transformation of work in terms of mass and velocity versus force and distance. The vector energy is not called energy. See link: http://en.wikipedia.org/wiki/Torque
What is mean by kinetic energy?
the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Energy that is in motion is what?
The kinetic energy of an object is the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity
What is needed to launch anything into space?
Energy enough to accelerate the object to an orbital velocity.
How are kinetic energy and heat related?
The kinetic energy of an object is the energy which it possesses due to its motion.It is defined as the work needed to accelerate a body of a given mass from rest toits stated velocity. Having gained this energy during its acceleration, the bodymaintains this kinetic energy unless its speed changes. The same amount of workis done by the body in decelerating from its current speed to a state of rest. Heat isused to create this substance
How is kinetic energy defined?
It is equal to one half of the mass times the velocity squared
What is the greatest of kinetic energy?
Kinetic energy is defined as 1/2mass times velocity^2 so either mass or velocity. Since velocity is squared it would be the main contributor. Ot sinply put because kinetic energy is the "energy of motion" velocity or speed would be the greatest contributor.
What is the greatest influience of kinetic energy?

A net force causes an object to?
Accelerate, motion is generated by applying force to mass.
How does the formula of kinetic energy define?
kinetic energy is defined as the energy possessed by a body by virtue of its MOTION Formula ;Ek=0.5xmassx(velocity)to the square
Energy can be formally defined as?
Kinetic energy is the amount of energy in an object due to its motion. It is defined as the amount of work that was required to accelerate the object from rest to its current velocity. In classical Newtonian physics, kinetic energy is calcualted in the following equation.Ek=1/2mv2Where:Ek is the kinetic energy of a body;m is the mass of the body; andv is the velocity of the body.Note that kinetic energy is always relative to the observer's frame of reference. For example, a girl holding a ball still would tell you the ball has no kinetic energy, because it is not moving - it has a velocity of zero, and according to the above equation, the kinetic energy must also be zero. Even if she were in a moving car holding the ball, she would still tell you (correctly) that the ball has no kinetic energy, because from her perspective, the ball is not moving. But from a bystander's perspective on the sidewalk, the ball (and the girl, the car, etc.) would indeed have kinetic energy, because, from the bystander's frame of reference, the ball is moving.
What are the conditions for an object to stay at rest to keep moving at constant velocity or the move with increasing velocity?
A body is moving at constant velocity including zero at Equilibrium Condition, No change of energy or zero force. With force a body can accelerate, move with increasing velocity.
How is energy defined in physics?
Energy is the capacity of an object to perform work.
