LESSON 2: ONE-DIMENSIONAL MOTION

ONE DIMENSIONAL MOTION

MOTION ALONG A STRAIGHT LINE

ONE DIMENSIONAL MOTION

CHANGE IN AN OBJECT’S POSITION ALONG A SINGLE STRAIGHT LINE

MOTION

ONE OF THE MOST FUNDAMENTAL CONCEPTS IN PHYSICS

MOTION

THE CHANGE IN POSITION OF AN OBJECT OVER TIME

SCALAR QUANTITY

PHYSICAL QUANTITY THAT’S DESCRIBED BY MAGNITUDE

SCALAR QUANTITY

FULLY DESCRIBED BY A NUMBER (MAGNITUDE) AND A UNIT

SCALAR QUANTITY

NO DIRECTION. E.G. DISTANCE, SPEED, MASS

VECTOR QUANTITY

PHYSICAL QUANTITY THAT’S DESCRIBED BY MAGNITUDE AND DIRECTION. E.G. DISPLACEMENT, VELOCITY, FORCE

DISTANCE

TOTAL PATH TRAVELED BY AN OBJECT

DISTANCE

TOTAL LENGTH OF THE PATH TRAVELED BY AN OBJECT

DISTANCE

HAS MAGNITUDE

DISTANCE

ALWAYS POSITIVE

DISTANCE

UNIT: Meter (m)

DISPLACEMENT

OBJECT’S CHANGE IN POSITION FROM ITS STARTING POINT TO ITS FINAL POSITION

DISPLACEMENT

HAS MAGNITUDE AND DIRECTION

DISPLACEMENT

CAN BE POSITIVE, NEGATIVE, OR ZERO

DISPLACEMENT

D = Xf - Xi

SPEED

DESCRIBES HOW FAST AN OBJECT MOVES

SPEED

DISTANCE TRAVELED PER UNIT TIME

SPEED

UNIT: m/s

SPEED

DISTANCE/TIME

AVERAGE SPEED

TOTAL DISTANCE TRAVELED DIVIDED BY TOTAL TIME TAKEN

VELOCITY

RATE OF CHANGE OF DISPLACEMENT

VELOCITY

DISPLACEMENT BASED

VELOCITY

RATE AND DIRECTION OF AN OBJECT’S MOVEMENT

VELOCITY

HOW FAST YOU’RE MOVING AND WHERE YOU’RE GOING

VELOCITY

V = D/T

VELOCITY

UNIT: m/s

ACCELERATION

RATE AT WHEN VELOCITY CHANGES WITH TIME

ACCELERATION

ANY CHANGE IN YOUR SPEED OR DIRECTION

ACCELERATION

UNIT: m/s²

ACCELERATION

a = Δv/Δt or a = Vf

POSITIVE AND NEGATIVE ACCELERATION

TWO TYPES OF ACCELERATION

POSITIVE ACCELERATION

VELOCITY INCREASES

NEGATIVE ACCELERATION

VELOCITY DECREASES

NEGATIVE ACCELERATION

DECELERATION
