What two quantities are crucial to quantifying the translational kinetic energy of an object?

Physics
1 answer:
Ostrovityanka [42]3 years ago
3 0

Answer:

Moment of inertia and angular velocity.

Explanation:

The translational kinetic energy of an object is possessed when the object is showing rotational motion. It can be given by the formula as :

KE=\dfrac{1}{2}I\omega^2

Here,

I is the moment of inertia of the object

\omega is the angular velocity of the object

So, the translational kinetic energy of an object is given by moment of inertia and angular velocity of the object. Hence, this is the required solution.

What is the gravitational potential energy of a 150 kg object suspended 5m above the Earth's surface
ella [17]
The gravitational potential energy referred to the ground level is given by
U=mgh
where m is the mass of the object, g=9.81 m/s^2 is the gravitational acceleration and h is the height of the object with respect to the ground.

Therefore in our problem the potential energy is
U=(150 kg)(9.81 m/s^2)(5 m)=7357.5 J

Describe the principle of conversation of energy:
exis [7]

Answer: Energy can neither be created nor destroyed, rather it is converted from one form to another

Explanation:

The principle of conversation of energy explains how energy is conserved in nature by being converted from one form to another such that no energy is created nor destroyed.

Practical examples include:

- electrical pressing iron that converts electrical energy to heat energy

- solar panels that converts solar energy to electrical energy

- Car batteries that converts chemical energy to light energy etc

A toy car moves 8 min 4 s at the constant velocity. What is the car's velocity?
Schach [20]

Explanation:

<u>Formula:</u>

velocity = (d \div t)

<u>d = distance given</u>

<u>t</u><u> </u><u>=</u><u> </u><u>the amount of time </u><u>given</u>

<u>Substitute the given values into the formula for velocity</u><u>:</u>

v = 8 \div 4

velocity is shortened for v.

8 (distance) divided by 4 (time) equals the velocity.

<u>Solve:</u>

2 = 8 \div 4

The velocity of the toy car equals: B. 2 m/s.
