The theory of impulse-momentum states that "t<span>he change in momentum of an object equals the impulse applied to it" meaning that the long barrel of the rifle covers a huge amount of motion of the bullet. The shot of the barrel is more accurate that way.
While work-energy theorem which states that "</span><span>the work done by all forces acting on a particle equals the change in the particle's kinetic energy" meaning that the discharge of the bullet caused by the barrel is slower but has more power than the one with the short barrel.</span>
Answer:4.7N
Explanation:both of the sides are equal
Answer:
i think the answer would be:Jonas’ brother gets out of the cab of the truck and sits in the back of the truck with the furniture. With less mass, they should be able to push the truck to the gas station.
Explanation:
Answer:
The same.
Explanation:
Temperature is a measure of the average kinetic energy of a substance; if two pieces of iron have the same temperature, then their particles will have the same amount of average kinetic energy.
Answer:
In the first law ,an object will not change its motion unless a force acts on it. In the second law force on an object is equal to its mass times its acceleration. In the third law ,when two objects interact , they apply forces to each other of equal magnitude and opposite direction
