|---|---|---|---|---|---|
| Final Velocity | The velocity that the object ends with after a change in its initial velocity is made.
🗑
|
||||
| Elastic Collisions | Very brief actions of two or more particles where they come in close position to one another, resulting in a change in momentum or exchange of energy. These "collisions" obey the law of conservation.
🗑
|
||||
| Gravitational Acceleration | The acceleration of an object's velocity caused by gravitational force. Acceleration due to gravity is symbolized by "g".
🗑
|
||||
| Momentum | A vector quantity that has the same direction as an object’s velocity; its magnitude is equal to the product of the object’s mass and speed: p = mv.
🗑
|
||||
| Initial Speed | The beginning or starting speed (magnitude of velocity) of an object before there is any change in its speed.
🗑
|
||||
| Final Speed | The speed (magnitude of velocity) that an object ends with
🗑
|
||||
| Initial Velocity | The beginning or starting velocity of an object before there is any change in its velocity (acceleration or deceleration).
🗑
|
||||
| Conservation Of Momentum | When no net external force acts on a system, the total momentum of the system remains unchanged. When two internal bodies interact and no external forces are acting on the objects, their total momentum remains unchanged.
🗑
|
||||
| Change In Velocity | Any change in the speed or direction of an object's motion; acceleration.
🗑
|
||||
| Average Speed | The average of the initial and final speeds of an object: image
🗑
|
||||
| Inelastic Collision | The usual case for collisions, in which kinetic energy is not conserved, but momentum is conserved.
🗑
|
||||
| Acceleration Due To Gravity | Commonly denoted by the symbol g; it is the same for all objects on Earth, regardless of their mass.
🗑
|
||||
| Acceleration | A vector quantity that represents the time-rate of change in the velocity of an object.
🗑
|
||||
| Free Fall | An object in free fall is considered to have no appreciable air resistance acting on it. All objects in free fall experience the same acceleration due to gravity.
🗑

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.
