Kinetic Energy: Example Problems

This video gives an explanation of kinetic and contains several examples for calculating kinetic energy, mass and velocity using the kinetic energy equation.

Kinetic energy is the energy an object possesses due to its motion. If an object is in motion then it has kinetic energy. It is also defined as the work needed to accelerate an object from rest to its known velocity. The object will maintain its kinetic energy unless a force acts upon the object to change its velocity. The same amount of work is done on the body when stopping it from its known speed to a state of rest. This is known as the work energy theorem.

There are different types of kinetic energy such as vibrational and rotational kinetic energy. This video will focus on translational kinetic energy. That is the energy of an object as it moves from one place to another.

Thank you for taking the time to explain this equation. Your presentation always great.

[hwburner]

thanks. i needed to figure this out in a pinch for physics. great job

[celeste]

I have a Physics test tomorrow and this really clarified and gave me good tips to follow thank you for the help!!!

[jonathonkhan]

Breathes in very hard 😮‍💨
Thank you sir for taking your time to make this video this was very helpful 🫠

[angelakate]

Thank you for this, this is so helpful and easy to understand. 💖💖

[irvinwong]

I have science finals tomorrow. Thank you for helping me relearn!

[iluis]

Thank you for making this just actually really helped

[aegchannel]

Thank you so much for teaching me and sharing this video! yay :D

how did u get 25 m/s at the last example? i thought we multiply 140 by 2 then divided by 0.45

45÷28000=512.2

sorry if im wrong but pls help me

[mrittika]

Thank you! It helped me a lot teacher.

[KulwinderSingh-miiw]

thank you so much sir for this explanation

[YahayaIdris-sdeh]

How do you know you are to divide the K.E
at the second example

[miraculouslucy]

Umm ..I don't understand what to use to get 120.000J ?
Is it division or multiplication?

[Yes_amyysimps]

Thanks, I'm here at 2022 and tryna understand this topic for my physics quiz.

[Starkcire]

Show your work step by step. So it's understandable

[jhoncarlotabug]

Answer 120.000 J this is correct or no

[wu]

You did a great job to explain it's just i have a hard time understanding

[NitinKumar-fyrh]

Thanku so much it helped me a lot ❤️❣️

[koreenadeleurme]

This really helped me thank you appreciate it sure wish there was someway you could click into the homeschool sites. You explained it so easy.

How do I know how much energy a joule is? If you say a joule is like a refrigerator sitting on ur head then I can grasp this.
