Motion
A place or object used for comparison to determine if something is in motion.
Reference Point
Which type of forces results in motion?
Unbalanced
You have a 10 lb ball, 20 lb ball, 30 lb ball, and 40 lb ball. Which has the most gravitational force?
40 lb ball
What is Newton's First Law of Motion?
Objects in motion stay in motion and objects at rest stay at rest unless an unbalanced force acts up it.
Name one of the two states that do not observe daylight savings time. If you can name both, double the points!

A distance covered within a certain unit of time.
Speed
In which situation is the object experiencing balanced forces?
A. A girl swings on a swing at the playground.
B. A car brakes as it approaches a traffic light.
C. A sled speeds up as it slides down a snow-covered hill.
D. A bus sits at a bus stop to pick up passengers.
D. A bus sits at a bus stop to pick up passengers.
The force of attraction that exists between two objects.
Gravity
What is Newton's Second Law of Motion?
Force = Mass x Acceleration

Are you moving right now?
It depends on your reference point!!!
In which situation is the object experiencing unbalanced forces?
A. A car slowing as it reaches a traffic light.
B. A car with its cruise control set to 30 km/h.
C. A penny at terminal velocity after falling off of a building.
A. A car slowing as it reaches a traffic light.
As the distance between two objects increases, the gravitational force between them...
Decreases
What is Newton's Third Law of Motion?
Every action has an equal and opposite reaction.

Which country is Stonehenge located in?
England
The tendency of an object to resist a change in motion.
Inertia
If one force pushes on a box to the right with 60 Newtons of force and two different forces push the box to the left with 30 Newtons and 20 Newtons, what will be the net force on the box? (Don't forget direction)
10 Newtons to the right.
What two factors affect gravitational force?
Mass and Distance
