Force & Distance
| Question | Answer |
|---|---|
| What is the force that pulls objects toward the earth? | Gravity |
| What is the force that resists the movement of objects against each other? | Friction |
| What is a change in position? | Motion |
| What is any object that makes work easier? | Machine |
| What is the weight of the object being moved? | Load |
| What is the force that causes and object to move? | Effort |
| What is a Push or a Pull? | Force |
| Something moves, when the forces acting on it, become________? | Unbalanced |
| It takes ___________ force to move a heavier object than it does to move a light object? | Greater |
| Using more force on an object increases the object's chang in ________? | Position |
| A _________ is a bar that turns on a Point? | Lever |
| The Point that a Lever turns on is called the _______? | Fulcrum |
| The amount of effort needed on a lever is determined by the ______ between the effort and the fulcrum? | Distance |
| When is work done? | Work is done when a force moves an object over a distance. |
| What determines the amount of work that is done? | Work is measured by HOW MUCH FORCE it takes to move something and HOW FAR it is moved. |
| Name four levers? | 1) Crow Bar 2) Hammer Claw 3)Wheelbarrow 4) Nutcracker Other 2 levers together are Scissors/ Tweezers/ Pliers |
| What is a Wheel and Axle? | It is a wheel with an axle, or rod running through the wheel. |
| One or more inclined planes used to force things apart? | Wedge |
| A bar that turns on a point? | Lever |
| A flat, sloped surface? | Inclined Plane |
| A wheel with a Groove that can hold a rope? | Pulley |
| A wheel with a rod running through it? | Wheel & axle |
| An inclined plane wound around an axle? | Screw |
| Wheel and Axles with "teeth" that work together are called ? | Gear's |
| When you turn the Axle of a wheel and axle, the wheel travels a greater____than the axle does? | Distance |
| Both fixed and movable puleys are used in a ________ ________? | Block and Tackle |
| A block and tackle allows you to use______ force when lifting an object because the rope moves a greater distance? | Less |
| An inclined plane lets you use less force to move an object because the load moves a greater __________? | Distance |
| The inclined plane part of a screw is called the ___________? | Thread |
| A __________uses the pointed part of one or more inclined planes to force things apart. | Wedge |
| A Wheel and Axle can increase the distance traveled while using less effort. In order to do this, the _______ needs to turn? | Axle Examples: Car wheels, bus wheels, ferris wheel |
| A wheel and axle can also be used to increase the effort instead of increasing the distance. In order to do this, the _____ needs to turn. | Wheel Examples: Steering wheel, screwdriver, doorknob |
| If you lift a box onto a shelf without using a pulley. What is the direction of your effort - Up or Down? | UP |
| If you lift a box, and use a Fixed Pulley. What is the direction of your effort - Up or Down? | Down |
| A Fixed Pulley changes the ___________ of the force needed to lift the load? | Direction |
| Where are the effort and load placed when using a Pulley? | At opposite ends of the rope that is wrapped around the Pulley. |
| When you turn the Wheel of a wheel and axle, the axle turns with more _____ than the wheel does? | Force |
