## Gravity

Parent Category: Physics
One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.
Pluto's mass is only about 1/455th of Earth's and its gravity would be 1/15th. Earth-type plants could grow immensely tall. Insects and animals could run faster and jump farther. However, the incredibly frigid temperature on Pluto (only 30 to 50°C above absolute zero) makes native lifeforms unlike…

Answer In the real world, the word 'weight' is commonly wrongly used interchangably with 'mass' as both are measured in kilograms. The formula is Force (weight in this case) = Mass x Acceleration. Force is measured in Newtons (N). Mass - the amount of substance - is measured in Kilograms (Kg) an…
