|---|---|---|---|---|---|
| What is Newton's First Law of Motion? | Objects in motion stay in motion, objects at rest stay at rest, unless acted on by an unbalanced force.
🗑
|
||||
| What is Newton's Second Law of Motion? | F=ma
🗑
|
||||
| What is Newton's Third Law of Motion? | For every action force there is an equal and opposite reaction force.
🗑
|
||||
| What does the acceleration of an object depend on? | The mass and net force
🗑
|
||||
| The greater the force...(acceleration) | The greater the acceleration
🗑
|
||||
| The greater the mass...(acceleration) | The greater the mass the lower the acceleration.
🗑
|
||||
| Forces come in __________. | Pairs
🗑
|
||||
| What is momentum? | A quantity that keeps objects in motion.
🗑
|
||||
| What does momentum depend on? | Mass and Velocity
🗑
|
||||
| The more mass... (momentum) | More momentum
🗑
|
||||
| The more velocity...(momentum) | More momentum
🗑
|
||||
| What is the letter symbol for momentum? | P
🗑
|
||||
| What is the Law of Conservation of Momentum? | During a collision momentum is transferred but the total momentum stays the same.
🗑
|
||||
| What is the Net Force of an object? | The overall force on an object.
🗑
|
||||
| Forces in the same direction... | add
🗑
|
||||
| Forces in opposite directions... | subtract
🗑
|
||||
| What is a force? | Any push or pull on an object.
🗑
|
||||
| What is an unbalanced force? | A non-zero net force (one force is stronger) that causes an object to accelerate.
🗑
|
||||
| What is a balanced force? | A net force of zero (all forces cancel out) that does not cause an object to accelerate.
🗑
|
||||
| What is a force diagram? | Shows all the forces acting an object with arrows where the length of the arrow represents the strength.
🗑
|
||||
| What is the Law of Electric Charges? | Like charges repel. Opposite charges attract.
🗑
|
||||
| What is an electric force? | Force that surrounds an electric charge with lines drawn from positive to negative.
🗑
|
||||
| As the size of the charge increases... (electric force) | As the size of the charge increases, the electric force increases.
🗑
|
||||
| As the distance increases... (electric field) | As distance increases, the electric force decreases.
🗑
|
||||
| What is static electricity? | The build up of stationary electric charges by gaining or losing electrons.
🗑
|
||||
| What is friction in relation to static electricity? | The transfer of electrons from one object to another by rubbing.
🗑
|
||||
| What is conduction? | The transfer of electrons from one object to another by direct contact.
🗑
|
||||
| What is induction? | The rearrangement of electrons in one object due to the electric field of a another object.
🗑
|
||||
| What is the Law of Magnetic poles? | Like poles repel. Opposite poles attract.
🗑

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.
