Newton’s Laws
First object in motion stays in motion, at rest stays at rest
Second f = m X acc (acc= force/mass)
Third action reaction forces
Force push or pull
Equation force= mass X acc
Label Newton (1 kg m/s/s)
Equation Mo= mass X vel
Tides caused by gravity from the moon
Universal Forces
Gravitational force pulling down, effective over long distances, depends on mass and distance
Electromagnetic repulsion of similar charges, opp attract
Strong nuclear Protons and neutrons
Weak nuclear nuclear decay
Projectile Motion initial forward velocity and pull of gravity
Ex: diagram
Friction force that opposes motion
Types fluid (fish), sliding, static, rolling
Strengths static is stronger than sliding
Law of Conservation Momentum momentum is conserved when objects collide in a closed system, loss of momentum by one object equals gain of momentum by another
Weight W=M X Acc due to gravity, less gravity = less weight
Inertia resistance of changes in motion
Air Resistance force pushing up on a falling object, increases with surface area, drag force
Terminal Velocity net force = zero
Balance Forces net force = zero
Net Forces sum of all forces acting on an object
Unbalanced Forces causes acceleration
Centripetal Force
Satellites acts as unbalanced force, changes direction, center directed force
Gravity Mass and distance
