  • What is gravity?

Agenda

Gravity

Gravity


Gravity1

Gravity

  • What is it?


Gravity2

Gravity

  • Gravity is the attractive force between any two objects that have mass.

  • depends on the masses of the objects and the distance between them.

  • Increases as mass increases or as the objects get closer.


Gravity3

Gravity

  • depends on

  • the masses of the objects

  • the distance between them.

  • Increases as mass increases or as the objects get closer.


Earth s gravitational acceleration

Earth’s gravitational acceleration

  • If you dropped a book and a piece of paper at the same time which would hit the ground first?

  • Take out air resistance. Now what?


Acceleration on earth due to gravity

Acceleration on earth due to gravity

  • Force of gravity on a falling object can be calculated with 2nd law equation

  • Fg = weight = mg

  • g = 9.8 m/s2 (On earth)

  • What about on Jupiter?


Gravity on other planets

Gravity on other planets


Mass vs weight

Mass vs Weight

  • The amount of matter an object contains

  • Will NOT change if you visit another planet

  • Measured in kg

  • Gravitational force exerted on an object

  • Will change if you visit another planet, because the acceleration due to gravity changes

  • Measured in N

MASS

WEIGHT


Weightlessness free fall

Weightlessness on the space shuttle

“Weightlessness” on the Space Shuttle…

  • Objects seem weightless (float around) on the space shuttle because they are in orbit with the space shuttle.

  • In other words, objects are in free fall…falling AROUND the Earth rather than downward toward it.
