Force Vocab
| Question | Answer |
|---|---|
| What are simple machines | Simple machines make work easier |
| what is mass | mass is the amount of matter that makes up an object |
| What is force | Force is a push or a pull |
| what is friction | friction is a force that causes objects in motion to speed up or slow down when two surfaces rub together |
| what is speed | speed is a measure of how far an object moves in a certain amount of time |
| what is motion | motion is a movement, or a change in an objects position |
| What is position | position is the place where an object is located |
| what is gravity | gravity is the force that pulls things down |
| What happens when more friction is present | The more an object slows down |
| What happens the lighter an object is | the less force you have to apply to get it in motion |
| What happens when there is more force applied | more energy is needed to put it in motion |
| What do forces do | they make things speed up, slow down, or change direction. |
| What do unbalanced forces do | they move |
| what do balanced forces do | they don't move |
| What is an example of a gravity vs. air resistance | a person parachuting |
| what is an example of a push vs. friction and gravity | a kid kicking a ball |
| what is an example of a pull vs. friction | A tow truck pulling another car |
| what is an example of a push vs. a push | a hand wrestling match. if someone used more force they would win |
| What happens when more force is applied | an object will go farther |
| How are unbalanced forces caused | it happens when one side has greater force in one direction. This will cause the object to move in the direction the grater force is going |
| What happens when there is more mass | the more mass the more force required to move the object |
| What are the different types of forces | magnetic force, pushes and pulls, gravity, air resistance, and friction |
| what does friction do | friction apposes motion between two touching objects |
| what does gravity do | gravity pulls everything toward earth. the more mass something has the more gravity acts on it. |
| what are balanced forces | balanced forces are when there are two equal forces acting in the opposite direction. |
| what is an example of gravity | gravity pushed down on the book. the table that the book is on pushes up. |
