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

VELOCITYWE CAN CALCULATE THE MOTION OF THE OBJECTS.

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.
