Definition
| the change in the velocity of an object that depends on the force & mass of the object |
|
|
Term
|
Definition
| the force that slows down the motion of an object flowing through air |
|
|
Term
|
Definition
the same speed and direction of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity.
The fastest an object can fall to the ground through the air |

Term
|
Definition
| an object is in motion when it travels around another object in a circle |
|
|
Term
|
Definition
an unbalenced FORCE that allows objects to move in a circular path.
Gravity pulls the planets around (orbits) the sun. |
|
|
Term
| Projectile motion
(Hint--don't forget the two parts) |
|
Definition
the curved path that an object follows when thrown,launched,or near the surface (horizontal motion) (vertical motion)
An object is thrown in a horizontal motion but gravity pulls it down in a vertical motion. |
|
|
Term
|
Definition
| a force of attraction between objects that is due to their masses |
|
|
Term
|
Definition
| a quantity defined as the product of the mass and velocity of an object |
|
|
Term
|
Definition
The likelihood of an object to keep moving or stay still until it is acted upon by an outside force.
the object doesn't want to move or if the object is moving it doesn't want to change speed or direction unless something acts on it |
|
|
Term
| Newtons 1st law of motion |
|
Definition
| An object at rest remains at rest and an object in motion remains in motion at the same speed and in a straight line unless acted on by an unbalanced force. Also known as Inertia |
|
|
Term
| Newtons 3rd law of motion |
|
Definition
| whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. |
|
|
Term
| The law of conservation of momentum |
|
Definition
| when a moving object hits another object some or all of the momentum of the first object is transferred (moved) to the object that is hit |
|
|
Term
|
Definition
| the motion of a body when only the force of gravity is acting on the body |
|
|
Term
| Newton's 2nd law of motion |
|
Definition
| the accleration of an object |
