Gravity and Electric
| Question | Answer |
|---|---|
| Gravitational Force | A force that pulls objects with mass toward each other, even when they are not touching. |
| Gravitational Field | The region around an object where gravity affects other objects. |
| What happens to gravity when mass increases? | The gravitational force becomes stronger. |
| What happens to gravity when distance increases? | The gravitational force becomes weaker. |
| Gravity depends on | The mass of objects and the distance between them. |
| Why objects fall toward Earth | Earth’s large mass creates a strong gravitational field. |
| When comparing two situations, what should you identify first? | What changed and what stayed the same. |
| If mass stays the same, what variable controls gravitational force? | Distance. |
| If distance stays the same, what variable controls gravitational force? | Mass. |
| If two objects are identical, what should you compare next? | Their distance apart. |
| If two objects have the same mass, what should you check next? | The distance between the objects. |
| When asked for the greatest gravitational force, what should you look for? | Large masses and small distances. |
| If distance is cut in half, what happens to gravitational force? | It increases. |
| What does a curved path show about motion? | A force is acting on the object. |
| Why gravity can act without contact | Objects are affected by a gravitational field. |
| Gravity vs distance graphs usually show | Force decreases as distance increases. |
| A flat line on a gravity graph means | The force is not changing. |
| Why gravity graphs are curved instead of straight | Gravity decreases faster at shorter distances. |
| A table showing increasing distance and decreasing force suggests | An inverse relationship. |
| Electric Charge | A property of matter that can be positive, negative, or neutral. |
| Like charges | Repel each other. |
| Opposite charges | Attract each other. |
| Neutral object | Has equal positive and negative charges. |
| Electric force | A force that acts between charged objects without touching. |
| Charging by friction | Rubbing objects together to transfer electric charge. |
| Charging by conduction | Transferring electric charge by touching. |
| Charging by induction | Rearranging charges without touching. |
| Which charging method does not require contact? | Induction. |
| If two objects repel each other, what must be true? | They have the same type of charge. |
| If an object is attracted without touching, what is happening? | Charge redistribution. |
| Why a charged balloon bends a stream of water | Charges inside the water rearrange. |
| What matters most in electric force questions? | Charge type and distance. |
| What does an electroscope show? | The movement or separation of electric charges. |
| Why do electroscope leaves spread apart? | Like charges repel. |
| What happens when a charged object is brought near an electroscope? | Charges move inside the electroscope. |
| Where do opposite charges collect during induction? | Closest to the charged object. |
| A force that acts without contact is called | A field force. |
| Why gravity and electric forces are similar | They both act through fields. |
| What evidence shows a field exists? | Motion changes without touching. |
| If an object bends, curves, or deflects, what does that show? | A force is acting. |
| If objects move without touching, what force is likely acting? | A field force. |
| Why gravity is not responsible for tape or balloon experiments | Gravity is very weak between small objects. |
| What pulling tape quickly causes | Transfer of electric charge. |
| What observation best supports electric force? | Attraction or repulsion without contact. |
| When objects are described as identical, what does that mean? | They have the same mass and properties. |
| If two identical objects are charged the same way, what happens? | They repel each other. |
| If two identical objects touch and then separate, what happens to charge? | The charge is shared. |
| If a charged object touches another object, the charging method is | Conduction. |
| If a charged object is brought near but does not touch, the charging method is | Induction. |
| If charges move within an object but no charge is transferred, this is called | Charge redistribution. |
| If an object changes direction, what does that show? | An unbalanced force is acting. |
| A curved path near a large mass is evidence of | A gravitational field acting at a distance. |
| When reading a table or graph, the strongest evidence comes from | Comparing one variable at a time. |
| If only one variable changes, the change in force is caused by | That variable. |
