Force by Mind Map: Force

1. Movement stops on earth no stop on space?

2. NO friction in space = no stop Earth = air friction = stop

3. Friction

4. no friction = infinite movement

5. 4 types of friction

5.1. sliding = 2 solid surfaces slide over each other

5.2. static = required energy to make something move, like a requirement for moving

5.3. Rolling = wheels on solid

5.4. Fluid = liquids or air against solid

6. Calculating force

7. Balanced and unbalanced forces

7.1. Balanced = no motion

7.2. Unbalanced = moving

8. you can tell direction and if an object is moving by its net force

9. push or pull

10. recorded by strength and direction

11. net force = total force from one or more objects

12. Newton

13. Unit for measuring force

13.1. used by all areas of the world

13.2. measured with a force meter

13.3. EX: 100N

14. Modernly famous for discovery of the laws of motion along with great enhancements for the discovery of gravity

15. two or more forces = add them together

16. 1st = inertia

16.1. all objects will resist a change in motion

16.2. at rest = stay at rest until something moves it

16.3. in motion = stay in motion until something stops it

16.4. depends greatly on mass

16.4.1. greater mass = more inertia ( or momentum )

16.4.2. less mass = less inertia ( or momentum )

17. Exertion of energy on an object

18. 2cnd = calculating acceleration

18.1. net force / mass = acceleration

18.2. measured in m/s squared

19. 3rd = every action has an equal and opposite reaction

19.1. you push something forwards = you go back

19.2. something rushing forwards has momentum

20. Momentum = inertia from movements, so that when it interacts with another object, that object is sent the opposite direction

20.1. momentum can be found through the formula, MOMENTUM = MASS*VELOCITY

20.2. when two objects with momentum collide they retain the same total momentum

21. Conservation of Momentum = due to something hitting another, there is an EQUAL reaction aka total momentum is the same

21.1. Recorded with kg * m/s

21.2. two objects with a momentum of 1 kg*m/s collide = 2 kg*m/s

22. Momentum can be transffered in different ways

22.1. two moving things = thing in front goes faster, thing behind still moves

22.2. one moving thing = front moves, back doesn't

22.3. attached = both move at same speed

23. Gravity = force pulling all objects to Earth and Earth to the sun

23.1. what makes us fall

23.2. necessary for movement

23.3. More mass = more gravity

23.4. all things have gravity
