Wormhole is a theoretical concept about teleportation from one place to another without travelling directly in the 3D space we perceive.

It serves as a portal to shorten the long distances between two points.

Black Holes were believed to have the strongest gravitational pull enabling a planet to be pulled inside and bringing to nowhere. And besides, scientists and astronomers are still unable to study this so-called Black Hole.

Balance force is a force that is at rest while the action and reaction is the interaction between two object and it is also known as The Newtons Third Law.

Using these formulas:

Work = Force x displacement

Work = mass x earth's gravity x height

PE = Force x height

Power = (Force x height) / time

Power = Energy / time

1. Find Work.

W = Fd

W = (47 N)(0.26 m)

W = Joule, use calculator

2. Find Work.

W = mgh

W = (20 kg)(9.81 m/s/s)(6.5 m)

W = Joule, use calculator

3. Find PE.

PE = Fh

PE = (25 N)(3 m)

PE = Joule, use calculator

4. Find Power.

P = Fh/t

P = (30 N)(10 m) / (5 s)

P = Watts, use calculator

5. Find Power.

P = E/t

P = 2,500 J / 25 s

P = Watts, use calculator
