IS IT MOVING?
BUT CAN IT MOVE?
HOW?WITH OUR HAND WITH OUR LEGS WITH THE WIND
Draw the MOTION of these objects.use
• The motion of the Skier
ARROWS
Motion of a traffic light.
Motion of the clockwise.
Motion of a canyon ball.
Motion of the space ship.
Motion of a softball.
Motion of the earth.
Motion of a spin.
The line or arrow used to describe objects MOTION is called TRAJECTORY.
And that line could be;
a straight line
a parabola
an oscillation
a circle
an ellipse

RECTILINIAR MOTION
OSCILLATING MOTION
ELLIPTICAL MOTION
CIRCULAR MOTION
PARABOLIC MOTION

VELOCITYWE CAN CALCULATE THE MOTION OF THE OBJECTS.
VELOCITY
TIMEVELOCITY = DISTANCE
TIME

DISTANCEIS EQUAL TO

A B
DISTANCE 100 METERS
TIME 14 SECONDS VELOCITY = 100 m14 s
VELOCITY = 7,14 m/s
VELOCITY = 7.14 m/s
HANDS ON! VelocityPROBLEM:
How do you identify and calculate the velocity of objects/bodies?
MATERIALS: Pencil and a calculator. STEPS: 1. Predict the velocity of this bodies looking at data. Write a number from 1 to 5 (from the faster to the slower).2. Calculate the velocity.3. Write a number from 1 to 5 (from the fastest to the slowest).4. Share and check the results with all the class.
