What must you apply to overcome Earth's gravitational force?

# data[].attributes.body
You must apply FORCES to overcome Earth's gravitational force.

# data[].attributes.headline
The bigger the mass, then bigger the what?

The bigger the mass, then bigger the what?

# data[].attributes.body
Gravitational force.

# data[].attributes.body
All MATTER has mas. Gravity is the result of MASS.

# data[].attributes.body
The force of gravity can change the MOTION of an object by changing its speed, direction, or both.

# data[].attributes.body
A force of attraction between objects

# data[].attributes.body
Make surfaces smoother.
Ex: Rough wood on a park bench

# data[].attributes.body
Substances that are applied to surfaces to reduce the friction.

# data[].attributes.body
- Tires push car forward

# data[].attributes.body
- It can cause holes in clothing.
-  Erosion of topsoil

# data[].attributes.body
Not moving.
Ex: Pushing a heavy piece of furniture without it moving.

# data[].attributes.body
Moving.
Ex: Sliding a book across a table

# data[].attributes.body
When a force is applied to an object

# data[].attributes.body
It can cause a moving object to slow down and eventually stop.

# data[].attributes.body
A force that opposes motion between two surfaces that are in contact.

# data[].attributes.body
When the net force on an object is NOT 0 N, the forces are unbalanced causing a change in motion.

# data[].attributes.body
When the forces on an object produce a net force of 0 N, the forces are balanced and will not cause a change in motion.

# data[].attributes.body
The combination of all of the forces acting on an object.

# data[].attributes.body
The SI unit for force

# data[].attributes.body
A push or a pull.

# data[].attributes.body
The acceleration that occurs in a circular motion.

# data[].attributes.body
final velocity - starting veloctiy/ time it takes to change velocity

# data[].attributes.body
The rate at which velocity changes over time.

# data[].attributes.body
Combine two velocities that are in the same direction, add them together.

# data[].attributes.body
The speed of an object in a particular direction.

# data[].attributes.body
Total Distance/Total time

# data[].attributes.body
The distance traveled divided by the time interval during which motion occurred.
D/T

# data[].attributes.body
An objects change in position relative to a reference point.

# data[].attributes.body
The object that appears to stay in place.
