|
Acceleration |
increase in the rate or speed of something. |
|
|
Deceleration |
Decrease in the rate or speed of something. |
|
|
Newton's First Law of Motion |
An object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an outside force. (The law of inertia) |
|
|
Newton's Second Law of Motion |
F = ma, or force equals mass times acceleration. (The law of acceleration) |
|
|
Newtons Third Law of Motion |
With every action, there is an equal and opposite reaction. (The action/reaction law) |
|
|
Friction |
The resistance that one surface or object encounters when moving over another. |
|
|
Force |
A push or pull on something. |
|
|
Unbalanced Force |
Forces that cause a change in the motion. |
|
|
Balanced Force |
Forces that are equal and don't cause motion with an object. |
|
|
Motion |
The action or process of moving or being moved. |
|
|
Net Force |
The total amount of forces acting upon an object. |
|
|
Isaac Newton |
The man that made Newton's three laws of motion; a rather famous physicist. |
|
|
Newton |
A measurement that measures force. |
|
|
Velocity |
The speed and direction of an object. |
|
|
Magnitude |
The strength of a force, but not the direction. |
|
|
Static Friction |
The friction acting upon an object when they aren't moving. An object needs to overcome static friction in able to move. |
|
|
Rolling Friction |
Rolling friction is the surface resisting the movement of something rolling across it, like roller blades on a wood floor. |
|
|
Sliding Friction |
Sliding friction is the surface resisting the movement of the object that is sliding over it, like a sled down a hill. |
|
|
Fluid Friction |
Fluid friction is when an object pushes water aside, like when you’re water skiing. |
|
|
Mass |
The amount of matter in an object regardless of weight or any forces acting upon it. |
