1 Is correct because James is going faster.
2 is correct because a faster speed on a position vs time graph will have a steeper slope
3 is correct as well.
The answer is 4 all of the above
Answer:
True
Explanation:
the horse pull on the wagon but friction and the wight + gravity make the wagon pull on the horse ( newton's 2ed law)
The correct answer would be B
Answer:
<u><em>Energy:</em></u> <em>It is the capacity of work done by the body, </em>
- <em>for example, kinetic energy, potential energy, thermal energy, and so on. The S.I. unit of energy is Joule.</em>
<u>Mechanical Energy: </u><em>Mechanical energy is the energy of the body corresponding to its motion or change in its position. </em>
- <em>For example, potential energy and kinetic energy.</em>
<em />
<u><em>Law of conservation of energy: </em></u><em>According to the law of conservation of energy, the net energy of the system remains conserved.</em>
<em />
- <em>For example, in the case of elastic collision, the net energy of the system is conserved before and after the collision.</em>
<u><em></em></u>
<u><em>Law of conservation of energy for moving object: </em></u><em>The net energy of the moving object remains conserved.</em>
<em />
- <em>For example, the net energy of the ball sliding down the hill without any loss of energy remain conserved.</em>
