Example? I see none, so I'll make up my own.
An example of kinetic energy, is like bicycle riding down a hill.
Kinetic energy, is basically <em>moving</em> energy.
Hope this helps!!!:)
A change of colour, heat being released or fizzing (a gas being released)
Answer:
The time is 0.90 sec.
Explanation:
Given that,
Height = 4.00 m
We need to calculate the time
Using equation of motion
For free fall, u = 0
Where, s = distance
g = acceleration due to gravity
t = time
Put the value into the formula
Hence, The time is 0.90 sec.
The answer is 24 J
F K =.25*8 N
= 2N
F = f k = 2 N
Since a = 0
W = f * s
2 N * 12 m = 24 J
The coefficient of friction is a ratio used to quantify the friction force among two gadgets when it comes to the everyday pressure this is keeping them collectively. The coefficient of friction is critical attention at some stage in material selection and floor requirement determination.
For instance, ice on steel has a low coefficient of friction – the 2 materials slide past each different without problems – whilst rubber on the pavement has an excessive coefficient of friction – the substances no longer slide past each other without difficulty.
The coefficient of friction is dimensionless and it does not have any unit. it is a scalar, meaning the direction of the force does not have an effect on the physical quantity. The coefficient of friction depends on the gadgets that are causing friction.

Answer:
rock will hit the ground at the same time.
Explanation:
given,
Jan throws rock vertically downward with some initial velocity(v).
Len throw rock at an angle of 30° with initial velocity(2 v) twice than the Jan
to find whose rock will hit the ground first.
it is given that rock is identical
now,
vertical component of velocity of the rock
= v₂ sin θ
= v₂ sin 30°
=
= v
hence the vertical velocity of the Len is same as that of Jan so the rock will hit the ground at the same time.
