- Write the given then substitute it. Multiply the value of velocity to itself and multiply by given mass and divide it by 2 to get the value of Kinetic Energy.
- What is the Kinetic Energy of a 1200 kg object that is moving with a speed of 24 m/s?
- Fruit hangs from a tree. The fruit is a quarter of a kilogram and is about to fall to the ground. If the fruit is 10 meters from the ground, how much potential energy does it possess?
- Write the given and remember the constant value of acceleration (9.8m/s2). Substitute the given and multiply it to get the value of Potential Energy.
- Given: KE = ? m = 1200kg v = 24m/sKE = ½ mv2KE = ½ (1200kg) (24 m/s)2KE = ½ (1200kg)(576))KE = 345,600 J
- GivenMass = 0.25 kgHeight = 10 mPotential Energy = unknownPE = mghPE = (0.25 kg) (9.8 m/s2) (10 m)PE = 24.5 J
- The students were happy that they got the correct answer and they went home safe and have a big smile in their faces.
- It's time to go home! Bye! Thank you Aina!
- Ma'am Rome will be happy to us!
- It's snack time!
- Bye!
- Bye!
- Yes, I learn it!
- Now, we can go home early!
- Bye!
- Yeah! Thanks guys.
- Bye!
- Welcome guys, take care! Bye.
- Wow! We got it guys!
- EXAMPLES OF POTENTIAL AND KINETIC ENERGY
- This is the formula for Kinetic Energy.
- KE =½ mv2Where: KE= Kinetic Energy v= velocity of concept m = mass of object
- Sure! Bring some snacks huh......hahahhaha
- Yeah, to answer our assignment.
- Aina, can we go to your house?
- We will bring a lot of snacks. Thank you!
- Are you done? Good bye Class!
- For your assignment copy this problem.
- ASSIGNMENT: What is the Kinetic Energy of a 150 kg object that is moving with a speed of 15 m/s?FORMULA: KE =½ mv2
- What is the Kinetic Energy of a 150 kg object that is moving with a speed of 15 m/s?
- Yes Ma'am!Goodbye Ma'am!
