Term
 Newton's First Law of Motion
Definition
 An object at rest remains at restAn object in motion keeps its velocity unless it expreiences a net force
Term
 Newton's Second Law of Motion
Definition
 The unbalanced force acting on an object equals the objects mass X acceleration
Term
 Newton's Third Law of Motion
Definition
 For every action force,there is an equal and opposite reaction force.
Term
 Ex. of Newton's 1st Law
Definition
 Bowling ball keeps rolling in the same direction unless it starts rolling on carpet because carpet has a net force
Term
 Ex. of Newton's 2nd Law
Definition
 If you push a sled with a smaller mass on it there will be a greater acceleration
Term
 Ex. of Newton's 3rd Law
Definition
 The action force is the swimmer pushing the water backward. The reaction force is the water pushing the swimmer forward.
Term
 Law of Universital Gravitation
Definition
 All objects in the universe attract each other through the force of gravity.
Term
 Gravity
Definition
 The force acting between all objects in the universe. Calculated by weight.
Term
 Weight
Definition
 The measure of the gravitational force excerted on an object
Term
 Vertical and Horizontal
Definition
