| 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 in 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 a force that pulls things toward Earth |
| The more friction present | The more an object in motion slows down |
| The lighter an object is | The less force you must apply to get it in motion |
| The more force applied | The more energy is released |
| What makes things speed up or slow down | Force |
| What makes objects change direction | Force |
| What kind of forces don't move | Balanced |
| What kind of forces move | Unbalanced |
| What are 2 types of magnetic forces | Push and pull |
| Does it require more or less force to move something that more mass | More |
| What pulls everything towards Eart | Gratvity |
| If you drop a bowling ball and a beach call odd the building, what would hit the ground faster? | Bowling ball because it has more mass |
| What does friction do? | It slows things down. |
| When do unbalanced forces happen? | When one side has greater force in one direction. |
| If you apply more force, what will happen to the object? | It will go farther |
| What are all the types of forces? | Magnetic force, pushes pulls, gravity, air resistance, friction |
| Without force, a still object would remain___ and a moving object would keep ___ | still, moving |
| Friction opposes motion between two __ objects | touching |
| Does gravity push you up or down? | Down |
| Are balanced forces two equal forces or unequal forces in the opposite direction? | Equal |
| Do unbalanced forces cause objects to move or stay still | Move |
