relationship between the energy of a object and the work done on it?
O
Work is needed for an object to keep a constant kinetic energy.
O
Work is needed for an object to keep a constant potential energy.
Increasing the kinetic energy of an object increases the amount of work needed to
stop it.
Increasing the potential energy of an object decreases the amount of work needed to
stop it.
HELP PLEASEEE

Increasing the kinetic energy of an object increases the amount of work needed to  stop it.

Explanation:

"Kinetic energy" refers to the energy of an object in motion while "potential energy" refers to the energy of an object at rest.  

Increasing the "kinetic energy" of an object means that more force has to be done in order to accelerate it. Using force means doing work. The more force is used, the more work is done. This also means that the "amount of work needed to stop the object will increase."

For example, when you suddenly push a cart in one direction, the kinetic energy is increased. If you push it harder, kinetic energy will increase further. This also means that an equal amount of work is needed in order to counteract the force, which is an increased amount of work that is essential for stopping the object.

So, this explains the answer.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
