Difference between increasing speed and decreasing speed on a graph 

# data[].attributes.body
change in velocity divided by time

# data[].attributes.body
increase in the rate or speed of something.

# data[].attributes.body
distance traveled divided by time

# data[].attributes.body
motion

# data[].attributes.body
SI unit force

# data[].attributes.body
sum of all forces acting on an object

# data[].attributes.body
have a smooth surface

# data[].attributes.body
direction

# data[].attributes.body
A force is expressed in newtons, can cause an object to speed up or slow down or change direction, and could be a push or pull

# data[].attributes.body
Weight is a measure of the gravitational force on an object

# data[].attributes.body
the rate at which velocity changes

# data[].attributes.body
Net force is determined by combining forces

# data[].attributes.body
The Newton is the unit of force

# data[].attributes.body
Friction opposes motion between surfaces that are touching.

# data[].attributes.body
The size of the force depends on the masses of the objects and the distance between objects

# data[].attributes.body
What keeps the planets moving in the sky?

# data[].attributes.body
Why do objects fall to towards the earth?

# data[].attributes.body
weight changes when gravitational force changes

# data[].attributes.body
measure of the amount of matter in an object

# data[].attributes.body
measure of gravitational force exerted on an object

# data[].attributes.body
a force of attraction between objects that is due to their masses
