That is called velocity. Which is acceleration in a direction.
Electrical energy, a form of kinetic energy results in a flow of electrons.
<u>Explanation:
</u>
Any kind of energy related to flow or motion of objects or particles falls under the category of kinetic energy. When an object undergoes motion or flow, it will exhibit velocity leading to kinetic energy, or energy utilized from the force applied for the motion.
In this case, the electrons will flow between the molecules due to the electric current supplied to it leading to the electrical energy, the flow of electrons generate current in opposing direction to the flow of electrons. Thus, current can be produced due to the flow of electrons on applying electrical energy.

1. the downward force is the force of gravity.
2. The upward force exerted is the Normal reaction from the floor.

g = 9.8 m/s²

F₁ = m₁ × g × sin(θ₁) </span><span>
F₁ = (2.3

F₂ = m₂ × g × sin(θ₂) </span><span>
F₂ = m₂ × (9.8 m/s²) × sin(70°) = m₂ × (2.86 m/s²) </span><span>
Then the total mass of the system is:
m = m₁ + m₂ </span><span>
m = (2.3 kg) + m₂ </span><span>
If it is given that m₂ slides down the incline, then F₂ must be bigger than F₁, </span><span>
and so the net force on the system must be:
F = m₂×(2.86
m/s²) - (21.18 N) </span><span>
Using Newton's second law, we know that
F = m × a
So if we want the acceleration to be 0.64 m/s², then
m₂×(2.86
m/s²) - (21.18 N) = [(2.3 kg) + m₂] ×
(0.64 m/s²) </span><span>
m₂×(2.86
m/s²) - (21.18 N) = (1.47 N) + m₂×(0.64
m/s²) </span><span>
m₂×(2.22
m/s²) = (22.65 N) </span><span>

Newton’s First Law of Motion - if an object is at rest, it takes un-
balanced forces to make it move. Conversely, if an object is moving
it takes an unbalanced force to make it change it’s direction or speed.
Newton was the first to see that such apparently diverse phenomena as a satellite moving near the Earth's surface and the planets orbiting the Sun operate by the same principle: Force equals mass multiplied by acceleration, or F=ma.
