Explaining Motion Revision. Forces. Forces arise from an interaction between 2 objects. In an interaction pair the forces are equal in size but opposite in direction. These forces act on different objects. They explain how rockets work etc. Forces (cont.).

ByChapter 27 Light. Early Concepts of Light. Ancient Greek philosophers thought that light consisted of tiny particles which could enter the eye to create the sensation of vision. Socrates and Plato thought that vision resulted from streamers emitted from the eye making contact with an object.

ByAverage Speed. total distance total elapsed time v = d/t. Average Speed (When only speeds are known). If only speeds are known, then the average speed is the sum of the speeds divided by the total number of values. FOR EXAMPLE: Find the average speed of 3m/s, 5 m/s and 8 m/s ?

ByGraphing Motion. Graphs. Graphs can show how objects change position or speed. (How far away was the turtle after 60 seconds?). Position-Time Graphs. Graphs often show how something changes with time. This graph shows how temperature changes with time in Santa Barbara, California.

ByReading Quiz. Which of the following statements is FALSE Speed, velocity, and acceleration are each defined as vectors "A car moving in a circle at a constant speed of 30 mph is accelerating "The instantaneous speed of a moving car can be different from its average speed. Newtonian Revolution.

ByAverage Velocity. Average speed is the distance traveled along its path divided by the time it takes to travel that distance Average velocity has both magnitude and direction + or – sign can signify the direction for linear motion. Instantaneous Velocity.

By0014 Force, Mass and Motion: 1. distinguish between mass and weight of an object. Quantity of matter in an object The measurement of inertia Brick = 1kg. The gravitational force exerted on an object by the nearest, most massive body (Earth) Brick = 2.2 pounds.

ByYear 10. May the force be with you!. Types of Force. A contact force requires objects to be touching for the force to have an effect. A field force will act at a distance – the field is the area within which the force has an effect. Types of force. Contact. Field. Magnetic Gravity

ByThe story so far…. Physics describes your world We can measure our world We use numbers and units to describe our world Next Measuring your position Measuring how your position changes with time. Position. Where you are Place on a map Place on an xy coordinate system. Distance.
