Term
 What are the scientific Derived Units?
Definition
 Speed - meters per second - m/sArea - square meters - m2Volume - cubic meters - m3Density - kilograms per cubic meter - kg/m3
Term
 What is a direct relationship.
Definition
 When the increase in one increases another. Example. When gas is exposed to an increase in temperature, it's mass increases.
Term
 What is an inverse relationship.
Definition
 When the increase of one decreases the other, or the decrease of one increases the other. Example. When you increase your speed, you decrease your travel time or when you decrease the amount of fluid in a glass, you increase the empty space.
Term
 What are variables?
Definition
 The changing conditions or quantities in an experiment.
Term
 What is an independent variable?
Definition
 The quantity or condition changed on purpose in an experiment.
Term
 What is a dependent variable?
Definition
 What is changed as a result of changing the independent variable.
Term
 What is the basic hypothesis of the Ptolemaic System?
Definition
 That each object in the sky moves on it's own imaginary sphere.
Term
 What are the boiling and freezing temperatures in Kelvin?
Definition
 Boiling - 373.15Freezing - 273.15
Term
 What is speed?
Definition
 How fast an object is moving.
Term
 What is velocity?
Definition
 An objects speed and direction.
Term
 What is acceleration?
Definition
 A change in an objects velocity (speed or direction).
Term
 What occurs when acceleration and velocity are in the same direction?
Definition
 Speed increases.
Term
 What occurs when acceleration and velocity are in different directions?
Definition
 Speed decreases.
Term
 What is force?
Definition
 A push or pull.
Term
 For an object to accelerate, it requires what?
Definition
 A force to act on it.
Term
 What are the characteristics of force.
Definition
 All forces have both direction and size (magnitude).
Term
 What do you call velocity at rest?
Definition
 Zero velocity.
Term
 What do you call velocity in movement?
Definition
 Non-zero velocity.
Term
 What are balanced forces?
Definition
 Forces that combine to produce a net force of zero.
Term
 What are unbalanced forces?
Definition
 When one or more of the multiple forces acting on an object are stronger than the remaining forces. Example: When picking up a mug off of a table, the force of the hand and the table is stronger than the gravity on the mass of the mug.
Term
 What is Newton's First Law?
Definition
 Also called the Law of Inertia. Net force on an object is the cause of acceleration. If an object is moving, it will continue to move at the same velocity from it's own momentum.
Term
 What is inertia?
Definition
 Inertia is the tendency to keep the same motion, or maintain the same velocity, whether the object is at rest or moving.
Term
 How is inertia measured?
Definition
 Intertia is measured by an object's mass. The larger the mass, the larger the inertia.
Term
 What is mass?
Definition
 Mass is the amount of matter in an object, not the weight. Weight is the amount of gravitational pull on an object.
Term
 What is weight?
Definition
 Weight is the amount of gravitational pull on an object, not the mass. Mass is the amount of matter in an object.
Term
 What is Newton's Second Law?
Definition
 The acceleration produced equals the net force in proportion to the mass.Formula: Acceleration = Net Force/Massor a=Fnet/m or Fnet=ma
Term
 What is Newton's Third Law?
Definition
 When an object exerts force on a second object, the second object exerts the same magnitude of force, in the opposite direction, on the first object.
Term
 What is friction?
Definition
 An opposing force on an object.
Term
 What is kenetic friction
Definition
 Moving friction. It is the force of friction between two objects moving against each other.The direction of kenetic friction is opposite of the direction the object is moving.
Term
 What is static friction?
Definition
 Stationary friction. It is the force that occurs between two objects that are touching, but not moving.
Term
 What are some characteristics of gravity?
Definition
 Gravity is an attractive force that pulls on an object instead of pushes.
Term
 What is Newton's Law of Universal Gravitation?
Definition
 The force of gravity between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them.
Term
 What is linear momentum?
Definition
 It is the mass of an object times its velocity.
Term
 What is the Law of Conservation of Momentum?
Definition
 Momentum is conserved when two or objects collide.
Term
 What is elasticity?
Definition
 It is the amount of bounce an object has after a collision.
