Gravity and Orbit
Would you weigh more pounds on Earth or the Moon?
Moon
Is weight and Mass the same thing?
NO!
Do objects pick up speed at the same rate even i they are different sizes and weigh different amounts?
Objects pick up speed at the same rate regardless of weight when gravity is the only force
According to Newton's law of gravity, how would the strength of gravitational force change if the earth moved farther away from the sun?
The force of gravitation between the earth and the sun would be less.
Does every object in the universe have gravity?
Yes even you
Is the Moon in a vacuum?
Yes!
An elliptical orbit is a what?
a curved, oval path
What did Sir Isaac Newton figure out?
how to measure the strength of gravitational attraction between any two objects. He found out gravity depends on only two factors. They are the mass of the objects and the distance between them
What does the force of gravity depend on?
mass of objects and their distance from each other
Anything made of ____________ has gravity
matter
An ellipse is a What?
oval shaped
What is mass?
the amount of matter in a object
What is Gravity, or gravitational force?
the force of attraction between two objects. It is the force that pulls ALL objects in the universe toward one another
What does and orbit depend on?
the force of gravity between the two bodies
What is weight?
the measure of the gravitational attraction of an object
What is the most deffinition of gravity?
the pull towards the center of Earth
What is a vacuum?
when there is no air or other gases present
Why didn't the flat piece of paper fall at the same rate as the crumpled piece of paper?
Air resistance.
Why do the planets continue to orbit around the Sun?
Because of the pull on the Sun's gravity.
