What was our average speed? Speed vs VelocitySlide 4: Velocity Speed and direction Vector quantity (must know direction) What are the 3 ways to change velocity? Copyright © Houghton Mifflin Company. All rights reserved.Newton’s First Law of Motion: Law of Inertia Every object continues in its state of rest or of uniform speed in a straight line unless a net force acts on it Things tend to do what they are already doing Newton’s First Law of MotionNet Force: Net force causes change in state of motion Units: pounds or newton (N) Net ForceObjects at rest: If net force is 0, object remains at rest ΣF=0 (sum of vector forces = 0) Mechanical equilibrium Bag of sugar on tension scale Downward force of gravity Upward tension (stretching force) Objects at restSupport Force: Object on horizontal surface Gravity (weight) pulls object down Support Force Upward force that balances weight of object on surface Must be equal to weight of object Normal force (perpendicular to surface) Support ForceObjects in motion: Object moving at constant velocity Space shuttle Static equilibrium—objects at rest Dynamic equilibrium—object moving at constant velocity Objects in motionObjects Move with the Moving Earth: Earth moves around the Sun, but so does everything on the surface of the Earth Objects in motion remain in motion unless acted upon by a force—Law of Inertia Examples: flip a coin in airplane, bird catching worm Objects Move with the Moving Earth You do not have the permission to view this presentation.
