Physics Unit 2 Constant Velocity

Science Starter! Complete the worksheet “Science Starter!” (on teacher’s desk).

Interpreting Motion Graphs {Forces and Motion. Distance vs Time Graphs The motion of an object is defined by its change of position over a period of time.

Principles of Physics.  motion along a straight line path, motion in one dimension  Which way are you headed?  How far did you go?  How fast are you.

Warm Up: 1. Use the word constant in a sentence, as you would use it in science. 2. Use the word “constantly” in a sentence as you would use in every day.

Graphing Motion. You will need: 3 colored pencils: red, blue, green A ruler if straight lines are important to you.

Diagrams and Motion Graphs.  The slope is equal to the acceleration.  Because we only consider constant acceleration, v/t graphs will always be straight.

Which line represents the greater speed? Graphing motion The greater the speed, the steeper the slope.

 Used to describe the velocity of a moving object during its motion.  depict the direction and relative speed by a vector arrow.

Warm Up – February 3, Speed-Time Graphs Motion and Acceleration.

Accelerated Motion. is changing either the speed or direction, or both, of motion. Acceleration is the rate of change of velocity, in other words, how.

White board the buggy lab . . . . On the board you should have: 1. One line of best fit graph. 2. Explain your graph. What is it showing? 3. What is your evidence?

Motion Maps

Motion Map Parts The dot: Indicates the position of the object The arrow: indicates the direction and speed of the object. (sometimes called a vector)

Dots and Arrows Together Dot alone = not moving. Dot and arrow together: Position, direction and speed.

Direction and Size Right = positive direction Left = negative direction The longer the arrow, the greater the velocity. SLOW FASTER FASTEST

The grid…. Motion Maps are drawn along a grid to show the position of the object. Draw a minimum of 3 arrows to show a pattern. Forward, Constant Velocity, Slow Forward, Constant Velocity, Faster

More Complicated Motion… The object moves forward at constant velocity, then stops and remains in place for two seconds, then moves backward at a slower constant velocity.

Example 1 Draw a motion map. The car is accelerating! Each successive arrow is longer, indicating the velocity is increasing. Draw a motion map.

Example 2 The car is accelerating! The car is NOT moving. Each successive arrow is SMALLER, indicating the velocity is decreasing over time. The car is NOT moving. A dot indicates time is passing, but no arrow means no velocity. The car is moving at constant velocity! The arrows are all the same size, this indicates that the velocity is NOT changing.
