All of the above, work is a measurement of energy transfer, in Joules.
Potential energy = Joules
Kinetic energy = Joules
The key thing here is that anything having to do with just energy or energy transfer is measured in joules.
Answer:
At the very beginning it is what states the whole life cycle
Answer:
No, some energy will be dissipated energy due to work of air resistance.
Same formula as the last question. x = vt + (1/2)at^2. In this case, v = 0, t = 12, and a = 2.0. Plug in the values and solve for x (which is change in position)
x = (0)(12) + (1/2)(2.0)(12^2)
x = (1/2)(2.0)(144)
x = (1)(144)
x = 144
So the car will travel 144 meters in 12 seconds.
Answer:
7. Net force: 14 N
Direction: Right
8. Net force: 360 N
Direction: Right
Explanation:
For Nm 7 the most force is on the right side so it has more power then left side and so its gonna pull towards the right side cancelling the force on the left. So it becomes 26-12 N = 14N
For Nm 8 all the force is on the right side so they add up.
