What are 2 ways gravitational potential energy affects us

Hey,

Gravitational potential energy is the energy of which something has depending upon how far away it is from the center of gravitation. For example, a piano would have just a sliver of GPE (gravitational potential energy) if it were only a centimeter above the ground, but if it were a mile above the ground it would go out with a bang.

The first way GPE affects our lives is a waterfall. You see, the water atop the waterfall is being pulled towards the earth and as it is it spreads out. Then it falls off the cliff and its GPE turns into GKE (gravitational kinetic energy, when soemething actually starts to fall) as it falls. If it weren't for GPE waterfalls couldn't exist.

The perfect example would be Newton's famous apple. as the apple hung from its tree, gravity pulled on it, and eventually, it fell. Its GPE turned into GKE as it fell towards Newton's head. Then came the realization of gravity to Newton.

If you have any questions i DEMAND that you tell me!

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
