1. Unit 6 Vocabulary Definitions

2. What you already know
Speed- how far you travel in a certain amount of time (distance/time)
Work- moving something over a distance
Motion- changing position

3. What you probably know, even if you're not aware of it
Velocity- the speed of something in a given direction
Acceleration- change in velocity (speed up, slow down, change direction)

4. Some brand new terminology
Force- push or pull on an object
Net Force- the total of the forces on an object
Balanced Force- object is still (net force=0)
Unbalanced Forces- object is moving (net force =/= 0)
Vectors- a value with magnitude and direction
Magnitude- how much

5. Newton's Laws
1- An object at rest, stays at rest. An object in motion, stays in motion. Unless acted upon by an outside force.
Inertia- a tendency to stay still
2- Force = mass x acceleration
3- For every force there is a paired force equal in magnitude and opposite in direction

6. Some common forces
Friction- force of things rubbing against one another
Air Resistance- the force of air against the object
Gravity- a field force dependent on mass

7. Learning Objectives
MS-PS2-2. Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
MS-PS2-1. Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.
