| Newton's 2nd Law of Motion |
|
Definition
A net force acting on an object causes the objedt to accelerate in the direction of the force.
F = ma |

Term
Newton's 1st Law of Motion
(The Law of Inertia) |
|
Definition
If an object is moving it will continue to move at a constant velocity unless a net force acts on it.
An object at rest will remain at rest unless a net force acts on it. |
|
|
Term
| Newton's 3rd Law of Motion |
|
Definition
| Action-Reaction pairs; for every action force, there is an equal and opposite reaction force. |
|
|
Term
| AIR RESISTANCE (Fluid Friction) |
|
Definition
| Frictional force air exerts on a moving object; acts opposite in the direction to the objects motion. |
|
|
Term
|
Definition
| The greatest velocity reached by a falling object. Achieved when the force of gravity is balanced by air resistance. |
|
|
Term
|
Definition
| Any object shot or thrown through the air, all projectiles have both horizontal and vertical velocities. |
|

Term
|
Definition
| Acceleration toward the center of a circle by an object moving along a circular path. |
|
|
Term
|
Definition
| The force that causes an object moving along a circular path to move towards the center of the path. |

| Man-made device that orbits Earth;used for communications, weather-monitoring.... |
|
|
Term
|
Definition
| A property of any moving object; the momentum (p) of an object is the product of its mass (m) and velocity (v). p = mv |
|
|
Term
| LAW OF CONSERVATION OF MOMENTUM |
|
Definition
| A law stating that the total momentum (p) of a group of objects is conserved unless a net force act on the objects. |
|
|
Term
|
Definition
| A measurement of the amount of matter in an object; SI unit - kg |
|
|
Term
|
Definition
| The mass per nitvolume of a material (g/cm^3)or (g/ml) describe how tightly packed a substanc's molecules are. |
|
|
Term
|
Definition
| Force exerted by every object in the univers on every other object. The amount of gravitational force depends on the masses of the objects and the distance between them. |
|
|
Term
|
Definition
| This is achieved when the upward push from air is greater than the downward push on the wing of a plane. |
|
|
Term
|
Definition
| The force that pushes a projectile (plane) forward. The opposite of drag. |
|
|
Term
|
Definition
| This force pulls an object to Earth at the rate of 9.8 m/s^2. |
|
|
Term
|
Definition
acceleration = force / mass
m/s^2 = Newtons / grams |
