Explain the relationship between energy and the potential to do work

1 answer:

4 0

Potential energy is the energy possessed by a body by virtue of its position or configuration . And energy is the capacity of doing work since power is work divided by time therefore change in potential energy divided by time is equal to the power of the object.

A car has a mass of 8000kg and a kinetic energy of 24,000j. What is the speed?

Oxana [17]

Answer:

2.5m/s

Explanation:

Kinetic energy = 1/2 mv²

Mass = m= 8000kg

Velocity(speed) = v =

K. E = 24000J

K. E = 1/2 x 8000 x v²

24000 = 4000 x v²

Divide both sides by 4000

V²= 24000/4000

V² = 6

Find square root of both sides

V = √6

V = 2.5 m/s

The S. I unit of energy is joules with symbol J

What is the temperature of a sample of gas when the average translational kinetic energy of a molecule in the sample is 8.37 × 1

-BARSIC- [3]

Answer:

404K

Explanation:

Data given, Kinetic Energy.K.E=8.37*10^-21J

Note: as the temperature of a is increase, the rate of random movement will increase, hence leading to more collision per unit time. Hence we can say that the relationship between the kinetic energy and the temperature is a direct variation.

This relationship can be expressed as

$K.E=\frac{3}{2}KT$

where K is a constant of value 1.38*10^-23

Hence if we substitute the values, we arrive at

$T=\frac{2/3(8.37*10^{-21})}{1.38*10^-23}\\ T=404K$

converting to degree we have $131^{0}C$
