FORCES AND MOTION LOOP SEQUENCE

-Motion is Relative...

-Pairs, 10 min.s How many ways are you and your partner moving right now?

-What about throwing a ball on a train? shoot car 90 ft going round curve?

Distance vs. Displacement

-How far is it to Mr. Merril's room? 3-d?

Speed = distance/time

-Average vs. Instantaneous

-Graphing Speed, distance/time,

-Meters/second

Velocity = Speed plus direction

-constant speed and constant direction

-If speed or direction is changing, velocity is changing

-Meters/second and direction

Acceleration = Change of velocity/Time interval (final speed - initial speed/ time)

-Change in velocity or direction

-negative acceleration and going around curves are acceleration

-Meters/second^2 and direction

-Free fall 9.8 m/s/s

-V=at and d=1/2at^2

Mass vs, Weight

-Mass is the amount of matter in an object

-inertia- the tendency of an object to resist a change in its motion

-More mass = more inertia

Momentum = mass X velocity

-p=mv

-the law of conservation of momentum

-the total momentum of objects is the same before and after a collision

-kg X m/s

Newton's First Law ( law of inertia)

Force = a push or pull

net force - combination of all forces, which direction

-balanced(equilibrium) and unbalanced forces

FIRST LAW: no net force , object remains at rest or in if moving, continues in straight line at same speed

Friction- Static friction, sliding friction, rolling friction, air resistence

Newton's Second Law Acceleration= net force/mass

Net Force = ma

-Measured in Newtons (N)

1 N = 1 kg X m/s^2

big and little masses fall at same speed= f/m = F/M

Weight= Gravitational force on an object = mass X 9.8 m/s^2

Calculate Acceleration a=Fnet/m=5 N/10 kg = 0.5 m/s^2

Circular motion, force pulls towards center(centralpetal force) satelites 8 km/s or 29,000km/hr

axis, rotation, revolution

see pg. 128 big book

Newton's Third Law

-Every action has an equal and oposite reaction

-pairs of force, interaction

-Action force, reaction force

Energy

-law of conservation of energy

-energy conversions

Work

force X distance

W=Fd

joule = Newtons X meters (N times m)

Balance and center of gravity
