Question  Answer 
Speed  Formula: D/T: Distance over time The measure of how fast an object is moving 
Velocity   Formula: v=d/t  Velocity = distance over time  a description of both speed and direction  Unit=m/s 
Acceleration  Formula: A=VfinalVinitial/Time  VfinalVinitial over time  measures how much an object's velocity changes over time 
Vector  direction 
Scalar  no direction needed 
Distance  how far an object moves in total 
Displacement  the distance an object moves from a starting position 
Friction Types  rolling sliding fluid/air static 
Rolling  Example: bowling 
Sliding  Example: Ice Skating 
Fluid/Air  Example: air or water resistance 
Static  initial friction when moving an object 
Forces  balanced vs. unbalanced 
Balanced Force  Two forces acting in opposite directions on an object 
Unbalanced Force  gravity or air/fluid friction 
Action  something that occurs 
Reaction  The result of an action or what happens because of the action 
Newton's Laws  there are three of them 
Newton's 1st Law  "An object in motion stays in motion, an object at rest stays at rest with the same speed and velocity unless acted upon by an unbalanced force(Gravity)"  inertia is the tendency of an object to resist change in its velocity: whether in motion or motionless 
Newton's 2nd Law  the acceleration of an object depends on the force acting on the object and the object's mass 
Newton's 3rd Law

For every action, there is an equal and opposite reaction 
Kinetic Energy   Formula: KE=1/2m X v^2 energy in motion/being used to create an action of some kind  measured in Joules 
Potential Energy  Formula: PE=mgh M= Mass G=acceleration of gravity(M/s^2) H= Height  Energy that is not being used  stored energy the higher something is from Earth's surface the more potential energy it has 
Momentum  Formula: P=mv M=Mass V=Velocity depends on objects mass and velocity  Newton called it the "Quantity of motion" 
Conservation of Momentum  states that any time objects collide, the amount of momentum stays the same, but can be transferred between the objects  conservation means that thing is not changing  So in the "Conservation of Momentum", the momentum is not changing it is constant
