The kinetic energy of an object is increased by a factor of 4 . By what factor is the magnitude of its momentum changed: 2.
<h3>What is kinetic energy?</h3>
- A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
- Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
- The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
- Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.

The answer to this question is True.
Answer:
its Y because the dot that represents it is close to S
Answer:
It is another machine that helps the main machine. Hope that helps!
Answer:
Explanation:
The work (W) done on the cube to be pushed across the floor is equal to the total thermal energy (ΔE) of the system:
(1)
Also, the work done on the cube by the horizontal force is giving by:
(2)
<em>where F: force applied to the cube , d: displacement of the cube </em>
<em>By equaling the equations (1) and (2)</em>, we can find the thermal energy of the floor:
So, the increase in the thermal energy of the floor is 51 J.
Have a nice day!
