Question

Why does a moving object come to a stop on a frictional surface?
The object’s kinetic energy is transformed into mainly heat energy.
The object’s potential energy is transformed into mainly kinetic energy.
The object loses all its energy in deformation.
The object’s kinetic energy is transformed into mainly potential energy.

Answer 1

it is a force that acts on the object, which over a distance removes energy from the object.
What kind of energy does a moving object have?
Where does that energy go?

Answer 2

B

Answer 3

is it a?

Answer 4

heat energy?

Answer 5

I'm confused what is it

Answer 6

@88019626 why did u say converted to kinetic energy?

Answer 7

i believe it would be a but don't quote me on it

Answer 8

hmm its definitely heat u lose potential energy for sure and by law of conservation of energy the last statement is incorrect

Answer 9

An object with a potential energy of 200 joules is dropped from a height of 2.00 meters. What is its kinetic energy when it reaches the ground?

Answer 10

@Ready!!!!! is the answer heat energy?

Answer 11

yes

Answer 12

is the kinetic energy 200 J?

Answer 13

idk

Answer 14

Energy before=Energy after
Energy potential=Energy kinetic

Answer 15

How much work is required to lift an object with a mass of 5.0 kilograms to a height of 3.5 meters?
17 joules
1.7 × 102 joules
1.9 × 102 joules
2.8 × 102 joules

Answer 16

W=F x d

Answer 17

idk how to plug that in

Answer 18

Force=5x 9.8

Answer 19

d=3.5

Answer 20

the answer doesn't make sense tho

Answer 21

W=5 x 9.8 x 3.5 -.-"

Answer 22

can u put that into a calc?

Answer 23

fine the answer is 171.5 joules -.-"

Answer 24

\[1.7 \times 10^{2} joules\]
