Part A
| Question | Answer |
|---|---|
| What are forces? | force = push or a pull that can act on objects |
| What are 3 thing for WORK to happen? | Distance, Movement, Effort |
| *What is Contact gravitational field? | A Contact gravitational field is a force that can that move a object from a touch or a contact when a force is getting applied on them. |
| What is non Contact gravitational field? | A non Contact gravitational field is a force that can that move a object without getting any touches or a contacts when a force is getting applied on them |
| Force of gravity = ? | Force of gravity = (mass of object) x (the strength of Earth’s gravitational field) |
| What are contact forces? | Contact forces must touch the object that they push or pull |
| What are non contact forces? | Action-at-a-distance forces can push or pull an object without touching it |
| What is Mass? | Mass is basically the amount of matter in an object/product |
| What is work? | A amount of effort spent when you use a force that causes an object to move a distance |
| How can work be Calculated? | (Work in joules) = (Force in newtons) × (distance in metres) And it stand for W = Fd |
| What is a First-Class lever? | - A first-class-lever has the fulcrum in between a input and output force |
| What is a Second-Class lever? | - A second-class-lever is the input and output force the same |
| What is a Third-Class lever? | - A third-class-lever is a input force between a fulcrum and output force, and the input and output force can be in same direction |
| What are the 3 class levers | First-Class lever, Second-Class lever, Third-Class lever |
| What are some parts of a lever? | Fulcrum, load, (outpost force), effort I+(input force) |
| What are some simple machines? | Wedge, Ramp, Pulley, Screw, Lever |
| What is a lever? | Lever's are basically a rigid bar that usually supported at one point |
| What is a Pulley? | A pulley consists of a grooved wheel with a rope or cable looped around it. |
| What is a Wheel and Axis? | The wheel and axle uses a shaft or axle that is attached to a bigger disk, called the wheel. |
| What is a Inclined Plane? | A surface that's sloped and it's an object that can move and it's also called a inclined plane |
| What is a Screw? | A screw is basically an inclined plane wrapped around a rod and this is called a continuous inclined plane, starting at the tip, and it's called the “thread.” |
| What is a Wedge? | A wedge is an inclined plane that travels through the object or material. |
| What is Distance? | Distance is the magnitude or the size of a displacement in between two places/positions |
| What is the formula for Work? | The formula for work is = Force x Distance |
| What is the formula for Mechanical Advantage? | The formula for Mechanical Advantage is F (out)/ F (in) Output Force/ Input Force |
| What is the formula for Ideal Mechanical Advantage? | The formula for Ideal Mechanical Advantage is D (in) / D (out) Input Distance/ Output distance |
| The difference between ideal mechanical advantage and mechanical advantage? | Ideal is input first then output and its also measured in distance. Mechanical Advantage is output first then input and it's measured in force. |
