Linear Motion

Linear MotionMoving things have two different kinds of motion•Linear Motion•Harmonic Motion•Motion is a change in position

in a certain amount of time

Linear MotionLinear Motion•Goes from one place to another

without repeating•Involves the concepts of distance,

time, speed, and acceleration

Linear Motion

What are some examples of Linear

Motion?

Linear MotionSpeed•Is the distance an object travels from one place to another over a period of time•Basically it means, HOW FAST

AN OBJECT IS MOVING

Linear MotionSpeed•Speed is a scalar quantity•An object with no movement at all

has a zero speed

What does Scalar mean?

Linear Motion

Linear MotionSpeed•Is calculated by taking the distance traveled divided by the time taken

Linear MotionVelocity•Is speed in a given direction•Is a vector quantity•Is the rate at which an object

Changes positon

EQUATION GIVES YOU IF YOU KNOWv=d/t Speed Distance timed = v x t Distance Speed and timet = d/v Time Distance and speed

A bike moves 50 meters in 5 seconds. Calculate the speed of the bike.

A car travels 60 m/s for 60 secs.Calculate how far it traveled.

A car travels 200 miles in 8 hours.Calculate the car’s speed.
