Forces and Newton's Laws
Forces
-
Action at a Distance Forces- Forces that cause an object to be moved, changed, or otherwise affected without being physically touched.
Gravitational Force- The force of attraction between all masses in the universe, especially the attraction of the Earth's mass for bodies near its surface. This is also the weight of an object,
-
-
Acceleration of Gravity- The acceleration of gravity is the acceleration of a body in free fall. On earth, the acceleration of gravity is -9.8 m/s/s
-
Electric Force- The attractive or repulsive interaction between any two electrically charged objects.
-
Magnetic Force- The attractive or repulsive interaction that arises between electrically charged particles because of their motion.
-
The Newton- The standard metric unit used for measuring the quantity of a force. It is equivalent to 1kg*m/s/s
Free Body Diagrams- Diagrams used to show the relative magnitude and direction of all forces acting on a object at a given moment in time.
Balanced Forces- When the forces on an object are balanced, the object is not accelerating. It could be stopped or traveling at a constant velocity. Balanced forces are equal in magnitude and opposite in direction.
-
Unbalanced Forces- When the forces on an object are unbalanced, the object is accelerating. It could be speeding up or slowing down. Unbalanced forces are unequal in magnitude.

Newton's Laws of Motion
Newton's 2nd Law: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Net Force- The vector sum of all forces acting on a a body. Any net force that an object is experiencing creates unbalanced forces.
Mass- The measure of the amount of matter in an object. Increased mass means increased inertia, as a massive object has a greater tendency to resist changed in its state of motion.

Newton's 3rd Law: For every action, there is an equal and opposite reaction.
3rd Law Force Pairs- Action reaction force pairs that are created by Newton's 3rd Law are equal in magnitude and opposite in direction. The force exerted on an object is the action, and the force experienced by the object as a consequence of Newton's third law is the reaction.

Newton's 1st Law: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Friction, Drag, and Inclined Planes
Friction
-
-
Coefficient of Friction (μ)- The ratio between the force necessary to move one surface horizontally over another and the pressure between the two surfaces.
-
-
-
-
Inclined Planes- Two forces of gravity are now created, one perpendicular to the object and one parallel to the object.
