An objects change in position relative to a reference point
What is motion
100
Newton is the measurement of this
What is force
100
When the hills and valleys of one object stick to the hills and valleys of another object
What is the source of friction
100
A force of attraction between objects that is due to their masses
What is gravity
100
Newton's law can be divided into how many parts to make it easier to understand
What is two parts
200
An objects that seems to stay in place
What is a reference point
200
The combination of all of the forces acting on an object
What is net force
200
Two factors that effect the amount of friction
What is rougher surfaces and more force
200
The effect on matter is this
What is pull all objects towards each other
200
Part one of this law states this
What is gravitational force increases if mass increases
300
the distance traveled divided by the time taken to travel that distance
What is speed
300
When the forces on an object does not cause an object to move
What is a balanced force
300
Friction between moving objects
What is Kinetic friction
300
The earth is large enough for you to notice this
What is gravitational force
300
Part two of the law states this
What is gravitational force decreases when distance increases
400
Changing speed or direction
What are two ways velocity can change
400
When the forces acting on an object cause a change in motion
What is an unbalanced force
400
Friction that causes an object to stay in place
What is static friction
400
Sir Isaac Newton
What is the name of the scientist who studied gravity?
400
This is a measure of gravitational force on an object
What is weight
500
The rate at which velocity changes over time
What is acceleration
500
An unseen force is called
What is gravity
500
To make a surface rougher does this
What is increase friction
500
Newton's law states: all objects in the universe attract each other through gravitational force and the size of this force depends on the mass of the objects and the distance between the objects
