Answer:
You're four sentences should include about how the roller coaster has the most potential energy at the top of the track, and the opposing energy, "kinetic" has the most kinetic energy when going down the hill.
Explanation:
Kinetic - In-Motion.
Potential - Gathering Energy to go into Motion.

Answer:
Explanation:
As the contour lines have roughly the same spacing but the actual topography is much steeper, the lines on the mountainous map represent a larger vertical spacing than the lines on the gradual hills.

Answer:
Explanation:
Given that,
The length of a simple pendulum, l = 2.2 m
The time period of oscillations, T = 4.8 s
We need to find the surface gravity of the planet. The time period of the planet is given by the relation as follows :
Put all the values,
So, the value of the surface gravity of the planet is equal to 
.
Answer:
The acceleration is g.
Taking the upward direction as positive
V = Vy y - 1/2 g t^2
Taking the downward direction as positive
V = -V y + 1/2 g t^2
One can choose either direction as positive, but the acceleration is
the same as g (it is g) while the projectile is in the air.
