Answer:
"The bowling ball on Earth will have a greater potential energy relative to the surface because the Earth has a much greater mass, and therefore a much stronger gravitational acceleration."
Explanation:
Potential energy acts as a result of the object placed over the Earth's surface, The object has the ability to fall because of the gravitational force. Gravitational potential energy is based on the weight of the object and also the height above the ground surface. But the elastic potential energy acts due to the shape of the object. Potential energy is related with the restoring of the forces which is the spring or the force of the gravity.
The temperature of the substance giving off the heat decreases while the temperature of the substance receilving the heat increases. they leach what is called equlibrium point where heat energy can longer be exchanged hence equql temperature. this isThermal physics

Answer:
Higher launch angles have higher maximum height
Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the maximum height.
A. We know that the height (h) = 25 m, and the distance (x) = 135 m.
B. We need to find the time flight first (t), then we can find easily the horizontal velocity (
. )
C. Because this is a projectile motions, so horizontal velocity is constant, but the vertical velocity is change because of the gravitational acceleration.
So we can use :
,
Note : Time that will be exist is a time from a land to the takeoff point, that can be called as the time flight.
Then we use,
, to find the horizontal velocity.
D. We know that :
, so by insert the numbers, and assune that the (g = 10 m/
), we get that ( t =
. )
After that by using
, we can get that
