Answer:
Acceleration is the rate of change of velocity. What is commonly said as ‘ten meter per second squared’ can bee broken down into ‘ten meter per second per second.’ This gives us the true meaning of the term acceleration.
Just like ‘ten meter per second’ means increasing the displacement by ten meters every second, ‘ten meter per second per second’ means increasing the velocity by ten meters per second every second.
So, basically if you consider the case of a free fall motion, where ‘t’ stands for time and ‘v’ stand for velocity at that instant:
At,
t=0, v=0 m/s
t=1, v=0+10 m/s;
t=2, v=0+10+10 m/s;
t=3, v=0+10+10+10 m/s;
This can also be thought as a Arithmetic Progression where common difference ‘D’ is the acceleration(a), since it adds a 10 m/s to velocity every second and the first term ‘A’ stands for the initial velocity (u). Using this approach we can derive to the first equation of motion:
v = u + at

Answer:How is potential energy converted to thermal energy in a system?
Explanation:
The acceleration of the body is provided by the tension in the rope.
<h3>What is centripetal acceleration?</h3>
The centripetal acceleration is given by a = v^2/r. v = velocity of the body, r = radius
a = (8.40 m/s)^2/(8.50 m)
a = 8.3 m/s^2
The tension in the rope is the force that provides the centripetal force in the rope.

Answer: Energy cannot be <u>created</u> or <u>destroyed</u> just <u>changes</u> in form.
Explanation:
This is the principle of the first Law of Thermodynamics, which relates the work and the transferred energy exchanged in a system through the internal energy, which is neither created nor destroyed, it is only transformed.
In other words: The total energy of a system is always conserved.
