Newtons 2nd Law
more force = quicker acceleration
Force = Mass X Acceleration
more mass = more force needed
acceleration is dependent on the net force acting upon it and the mass of the object
Newtons 3rd Law
Things can move because there's more going on than just the action and reaction forces
F^n (net force) = F^t (tension force) - M^o (mass of object) X gravity
For every action; there's an equal and opposite reaction
Newtons 1st Law
Objects in motion stay in motion
Simple Takeaway: If there is a net acceleration in some direction, there must also be a net force in that direction
Moving objects don't spontaneously
-Slow down
-Speed up
-Change Direction
Law of inertia
Types of Forces
Contact Forces
Tension
: String, Rope, Or Cord
Spring
: Power exertex by a compressed or stretched spring
Friction
: Objects moving on objects
gravity
: the force attracting two objects together. The more mass an object has, the stronger it's gravitational force.
Normal
: Push back of objects
applied
: force applied by a person or another object
Air Resistance
: Air pushing on moving object
Action at a Distance Forces
Electrical
: Power that is exerted between two charged objects
Magnetic
: Attraction or repulsion between electrically charged objects
Gravitational
: On any planet or area that has gravity
Net Force= Larger force- Smaller force
