Question

Which of the following represent kinetic energy?

A) water behind a dam
B) a roller coaster at the top of a hill
C) gasoline
D.) Riding a bicycle
E.) An apple falling from a tree
F.) Wind

Answer 1

D, e, and f cause the object of energy is motion, in which of these cases would be anything that can travel

Answer 2

Step-by-step explanation:

Kinetic energy is the energy obtained by an object due to its motion or movement.

Mathematically, Kinetic energy =
`(1)/(2)mv^(2)`

where m = mass

v = velocity

When a person is riding a bicycle then cycle will move from its position, therefore, it will have kinetic energy.

When an apple falls from tree then it will also have kinetic energy as apple is moving from its position.

Wind will also have kinetic energy as wind moves from one place to another.

Thus, we can conclude that following represent kinetic energy:

• Riding a bicycle.

• An apple falling from a tree.

• Wind.
