Term
 Acceleration
Definition
 velocity/time mesured in m/s^2
Term
 Positive Accleration
Definition
 Graphed with a positive slope
Term
 Negiative Accleration
Definition
 Graphed with a negative slope
Term
 Flat Line
Definition
 Going at a constant speed
Term
 Velocity-Time Speed-Time
Definition
 The types of graph you use to show Acceleration
Term
 Force
Definition
 Energy exherted on a object to make things stop, or go.
Term
 Push and Pull
Definition
 The two types of forces there are
Term
 Unbalacnced Force
Definition
 Forces are unbalanced, and now an object is either moving or stopping
Term
 Balanced Force
Definition
 Forces are all equal in size and direction and the object is not moving
Term
 Net Force
Definition
 Chaos, every thing will have a different speed, direction now.
Term
 Friction
Definition
 A force that oppses motion between two forces. 3 types of Friction
Term
 Sliding Friction
Definition
 Depends upon the wieght of the object and the surface that the object is on. Rough=more frictionSmooth- less friction
Term
 Rolling Friction
Definition
 Oppses motion less than sliding Friction. Basically sliding motion, but with a wheel.
Term
 Liquid Friction
Definition
 Has a lubricant, like oil, hand lotion or something of the like.
Term
 Sir Isaac Newton
Definition
 MathematicianFocus on gravity, Motion,speed and acceleration
Term
 Inertia
Definition
 the property that makes things move or makes things stop. dependent on mass
Term
 First Law of Motion(Law of Inertia)
Definition
 All objects in motion will stay in motion, and all objects at rest will stay at rest, untill the are met with an unbalanced force
Term
 Newtons
Definition
 wieght is measured in Newtons. 1 newton is about 9.8 kg 1 kg is about 2.2 lbs
Term
 Second Law of Motion
Definition
 Force (measured in N)= Mass(kg) x acceleration (m/s^2)
