Well, kinetic energy is defined as energy in motion (or as you said, action energy). Now, in order to characterize something as kinetic energy, it needs to be in motion (e.x., movement on a rollercoaster, a ball falling, a ball rolling, a person running, or a car in motion, really, anything moving).
Potential energy is stored energy. For example, it could be the farthest point back when you pull a slingshot. Or being at the very top of a hill right before you fall back down it, or holding a ball at its highest point before you drop it. Another example, is water stored behind a dam waiting to be released. Hope this helps!
Answer:
no because there are large ones middieum and small but they're mostly large
Explanation:
Answer: a) close together
Explanation: The electric field lines also represent the intensity of the field, in this sense for strong electric fields it is usually draw the lines close to each other. In constrast when they are far apart the electric field is weak.
Answer:
5.625km/h
Explanation:
We are given that
Distance between home and market, d=2.5 km
Speed, v1=5km/h
Speed, v2=7.5 km/h
We have to find the average speed of the man over the interval of time 0 to 40min.
Time,
Using the formula

1 hour =60 min

Distance traveled by man in 10 min with speed 7.5 km/h=
Therefore,
Total distance covered=2.5+2.5/2=3.75 km
Time=40 min=40/60=2/3 hour
Average speed=
Average speed=
