What is gravity?
Anything that has mass exerts a force of gravity and can exert that force on other objects
anything without mass exerts a force
The fewer matter an object has, the more gravity it has
What does the standard definition of gravity indicate?
It does not matter how small it is, it has gravity.
The greater mass of the body, the greater the force exerted
The more matter an object has, the less gravity it has
How does mass affect the force exerted?
mass
the more matter it has the more gravity it has
Friction between two bodies.
distance
Whether the object is metal or not.
What factors affect gravity?
Yes all bodies exert gravity regardless of size and mass.
Yes, as long as it is big enough.
Yes, as long as it is magnetic.
Yes, as long as it is close enough.
Do all objects exert gravity?
distance
If two objects are too far, gravity cannot act between them. 
If two objects are touching, gravity cannot act between them.
What would keep gravity from affecting two objects?
Friction only occurs between objects that are touching. Gravity can act between objects that are not touching.
Friction only occurs between objects that are not touching; Gravity can act between objects that are touching
friction occurs everywhere
How do gravity and friction differ?
no
yes
Does size matter as to whether or not an object has gravity?
yes
no
Would a planet have more gravity than a pencil?
Any object exerts gravity on other objects no matter how small it is, and the more matter an object has, the more gravity it has.
there is a pull
gravity causes an attraction between two masses
there is friction
friction causes an attraction between two masses
How do objects interact under gravity?
friction only occurs that are touching
Friction only occurs between objects that are touching but gravity can act between objects that are not touching.
friction occurs everywhere
How is friction different from gravity?
any object has gravity no matter how small it is
no
Friction only occurs between objects that are not touching
yes
Does size matter when it comes to gravity?
The earth has a lot of gravity, the more matter an object has the more gravity it has
yes
no
Does the earth have gravity?
have a push and pull
exert and attraction and pull on other objects
an attraction
a friction
nothing
What does an objects gravity cause it to do?
So what is gravity? A typical definition of gravity is that it is a force. It causes an attraction between two masses. According to this definition, anything that has mass exerts a force. Any object exerts gravity on other objects. It does not matter how small it is, it has gravity. The more matter an object has, the more gravity it has. Your pencil has a tiny bit of gravity, but far too little to notice. What about a planet? It would have a lot of gravity. An objects gravity exerts a pull on other objects. Friction only occurs between objects that are touching. Gravity can act between objects that are not touching. In fact, gravity can act over very long distances. Where else can you feel gravity?
