Motion, Speed, & Velocity. Motion Motion is a change in position (relative to a reference point) *reference point- stationary (still) object.

 Please have a seat.  What is the change in velocity of a car that accelerates 50 m/s 2 for 0.25 seconds?  What is the speed of a car traveling 100m.

MOTION Motion: Change in position over time and is described by speed, velocity and acceleration.

Motion Definition Speed A change in position over time Measures the rate of motion (how fast something is going) Speed = distance (miles, km, m, in, cm,

Chapter 1: Matter in Motion  Motion= a change in position over time  Reference point= an object that stays in place and shows us that something is moving.

Speed Velocity and Acceleration. What is the difference between speed and velocity? Speed is a measure of distance over time while velocity is a measure.

Measuring Motion

Some vocab words coming up… Motion- an objects change of position relative to a reference point Usain Bolt- probably winning a race or something like that

Frame of Reference- a way to specify the precise location of objects in space Somebody foolishly frolicking on the beach

Distance vs. displacement… Distance- how far an object moves Displacement- the overall change of position of an object (direction included) Blue Line = Displacement Black Line = Distance traveled

Distance vs displacement Distance = a length (and nothing else) (14 miles) Displacement = a length plus direction (14 miles West)

Distance or displacement? 76 km North = _______________________ 34 mi =_____________________________ 40,123 meters =________________________ 3,212,532 miles Southeast=______________

Let’s do a sports analogy… Hit a home run… Distance 360 feet (90X4) Displacement = Zero! Started at home, ended at home Hit a single… Distance = 90 feet Displacement = 90 feet NE

Speed vs Velocity It’s real, real simple. Speed- DISTANCE traveled over a specific time Velocity- DISPLACEMENT over a specific time 15 mi/hr  speed 15 mi/hr SOUTH velocity

Review… Speed = distance/time Distance = magnitude only (Scalar) Velocity = displacement/time Displacement = magnitude plus directi0n (Vector)

Review…
