|---|---|---|---|---|---|
| Speed | The rate at which an object moves
🗑
|
||||
| Average Speed | Speed=Difference/ Time
🗑
|
||||
| Velocity | Tells the rate an object moves and in which direction it moves
Think of a air traffic controller
🗑
|
||||
| Acceleration | Change in velocity (speed and direction) and direction of an object
**A car going at the same speed but turning*
🗑
|
||||
| Force | The push or pull between objects
🗑
|
||||
| Mass | The amount of matter making up an object
🗑
|
||||
| Independent Variable | What you change in your experiment or it´s the variable that you´re testing
🗑
|
||||
| Dependent Variable | It´s what we measure: the information you put in the data table *changes the independent variable doesn´t depend on anything else (stands alone)
🗑
|
||||
| Inertia | 1)The tendency of ALL objects to RESIST a change in motion 2) the MORE mass an object has the the MORE INERTIA IT HAS
🗑
|
||||
| Newton's First Law | Effect of balanced and unbalanced forces on an object at rest ans on an object in motion
🗑
|
||||
| Newton´s Second Law | The amount of force needed to accelerate an object. It depends upon a mass of the object.
🗑
|
||||
| Mass VS. Weight | Mass: Does not change with location
Weight: It does change with location. A measure of the force of gravity.
🗑
|
||||
| Balanced Forces | There is no motion
🗑
|
||||
| Unbalanced Forces | One side powers the other
*So it will move to he side that pushes harder.
🗑
|
||||
| Energy | Ability to do work or to cause. Exists in many forms.
🗑
|
||||
| Frame of reference | The point of view which you observe motion
Example: ¨You are traveling north and your friend are not moving. That's because you and your friends are in the same reference frame.
🗑
|
||||
| Resultant | Occurring or produced as a result or consequence of something
🗑
|
||||
| Vectors | Magnitude & the direction of the force 10 N R (vector)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
