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
