Question

Select the correct answer from the item bank to fill in the blanks to complete the following paragraph. 200 joules 100 joules K=1/2mv² U=mgh heat 1. 2. 3. 4. 5. A 2-kg object is dropped from a height of 10 meters. The potential energy can be calculated by using the formula _____ The potential energy is calculated as ______________ (use g=10m/s²for your calculation). If the object strikes the ground with a speed of 5 m/s, then using the formula __________, the kinetic energy is 100 joules. This requires that ________ energy is turned into _of and eventually released to its surroundings.​

Answer 1

1.
`mgh` \\

2.
`200 Joules`\\

3.
`(1)/(2) mv^(2)` \\

4.
`100 Joules`\\

5.
`heat`

Answer 2

1. U=mgh

2. 200 (if u use mgh (m is mass g is gravitational field strength and h is height) it will be 2×10×10)

3. k= 1/2mv2 the third one

4. 100 J

5. Heat (property of heat is to be released to the lower concentration area)
