Science: Force, gravity, friction, and Newton's Law Study Stack
| Question | Answer |
|---|---|
| What is any use or pull/ an action that can change motion? | Force |
| What is the sum of all the forces acting on an object? | Net force |
| What is the unit for Force | Newton |
| What is the force applied and the object doesn't mov? | Balances forces |
| What is force applied and the object moves int the direction of the force? | Unbalances forces |
| What is a force that opposes motion cause by rubbing 2 objects together? | Friction |
| What is a term used to measure the ability of an object to resist a charge in its state of motion? | Inertia |
| What is an attractive force between any two objects that depends on the masses of the objects and the distance between them? | Gravity |
| What is the amount of matter in an object? | Mass |
| What is the gravitational force exerted on an object? | Weight |
| Identify Newtons's 3 laws in these examples: -a rocket blasting off from earth -a golfer using a bigger swing to drive the ball to the fairway - The football will remain in motion util the unbalanced force of gravity stops it | - 3rd law - 2nd law - 1st law |
| It takes _______ force to accelerate a light object | less |
| It takes _______ force to accelerate a heavy object | more |
| As mass is ________ acceleration decreases | increases |
| As mass is ________ acceleration increases | decreases |
| What is the formula for Force? | Force = mass x acceleration |
| What is the formula for Weight? | Weight = mass x gravitational strength |
| What is the number an units for gravitational strength? | 9.8 m/s/s |
| What are the 4 types of friction? | Static friction; Sliding friction; Rolling friction; Fluid friction |
| Explain what frictional forces a truck might experience as more weight is added to its bed? | As more wight is added to the truck, more force pushes the tires against the road, resulting in more friction. The truck also experiences fluid friction |
| What are some thing you can do to increase frictional force to be helpful? | Add salt to an icy sidewalk; have treads on tires |
| What are some things you can do to decrease fractional force to be helpful? | Use a dolly under a washing machine while moving it; Use a lubricant for the engine of a car; Activate the air jets for an air hockey game |
| What is the Law of Universal gravitation? | Any two objects attract each other bases on mass and distance. Mass increase for of gravity |
| As you increase the mass of an object what does this due to its force of gravity? | As you increase the mass, the gravitational force increases |
| As you increase the distance between objects, what does this do to the force of gravity? | The force of gravity decreases. |
| What does Newton's First Law state? | An object at rest will remain at rest unless acted on by an outside force |
| What does Newton's Second Law state? | If you apply more force to an object, it accelerates at a higher rate |
| What does Newton's Third Law state? | For every action there is an equal and opposite reaction |
| Explain using Newton's Laws, if a golfer adjust his wing what will happen? (Short Answer) | If he uses more force there will be more distance, and if he uses less force there will be less distance. |
| Explain how wearing a seatbelt in a moving car demonstrates Newton's first law of physics. (Short Answer) | The passenger remains in motion, unless the unbalanced force of the seatbelt troops him. If the seatbelt didn't stop him he would fly out the windshield. |
| Does balanced forces create movement or no movement? | No movement |
| Does Unbalances forces produce movement or no movement? | Movement |
