Answer:
Is the equation for Ec=1/2 m(Dv)^2 where Dv is the difference between the angular speed & the areolar speed?
"Speed" is the rate at which distance is being covered .... the ratio
of distance covered to the time it takes.
"Velocity" is the rate at which distance is being covered .... the ratio
of distance covered to the time it takes ... AND the direction in which
it is covered. 'Speed' with the direction of the motion.
Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.

Image distance 
Height of image 
Generally the lens equation is mathematically given by
Where 
is Subject
Therefore the distance between the person and the car is
Explanation:
Dark Energy. Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity. It has been hypothesised to account for the observational properties of distant type Ia supernovae, which show the universe going through an accelerated period of expansion
