Answer:energy which a body possesses by virtue of being in motion.
Explanation:
Answer:
Friction
Explanation:
As the toy cars rolls away, more friction is created. The more friction there is, the more friction on surface rubs against another which creates friction which in-term slows it down. Hope this helps.
Answer:
Explanation:
Refraction: It is a process in which light ray travel from one medium to another medium.
When a light travel form one medium to another medium then the speed of light changes.
When a light travel from rare to denser medium then the light bend towards normal .
When a light travel form denser to rare medium then the light ray bend away from the normal.
Refractive index:It is a ratio of velocity of light in vacuum to the velocity of light in medium .It is a measure of change in speed of light when it passes from vacuum into material.It is represented by "n''.
Mathematical representation:
Where n=Refractive index of material
c=Velocity of light in vacuum
v=Velocity of light in medium
Answer:
Because you need to have that momentum to decease over a little bit of time because if it doesn't have room to move backward, that force isn't going to reduce and it will hurt very badly.
The statement that best describes Keisha errors is an object in either state of equilibrium must have no net force acting on it.
<h3>What is an object at dynamic equilibrium?</h3>
An object is said to be on a dynamic equilibrium when it moves at a constant speed, and all the forces on the object are balanced.
An object is also said to be on static equilibrium when it is unable to move because all the forces which act on it compensate for one another.
Therefore, the statement that best describes Keisha errors is an object in either state of equilibrium must have no net force acting on it.
