Gravity and Friction

A push or pull that changes motion,shape,and direction

What is force

hitting a baseball with a bat

contact force example

Gravity pulling on a falling apple

noncontact force example

Gravity depends on mass and distance

what does newtons law of universal gravitation state

it gets weaker

what happens to gravitational force if two objects move farther apart

false

gravity only exists on earth

true

the more mass an object has,the stronger its gravitational pull

friction is a nonconatct force

false

the moon has less gravity than earth

true

newtons law helps us see God’s order in the universe

true

what are some contact forces and non conatct forces

contact forces- friction. noncontact forces- gravity pulling on an apple

what is the law of universal gravitation

all objects pull on eachother the bigger the mass,the closer they are the stronger the pull

how does friction affect the motion of two objects sliding past eachother

resist the motion between 2 objects sliding past eachother

gravity

a force between objects due their masses

mass

the amount of matter in an object

friction

a force that resists motion between two touching surfaces

weight

the gravitational force on an object

contact force

a force that happens when objects touch
