2 Dimensional (Projectile) Motion

 Galileo discovered that mass does not affect the time it takes for an object to fall to the ground.  Objects fall at the same rate (on earth it is.

What would happen if you jumped into a well that went all the way through Earth? See answer in video.

Freefall Any object which is free to fall will be accelerated downward at 9.81 m/s 2. (Neglecting air friction) Every second the speed increases by 9.81.

AGENDA NOVEMBER 9 Go over D problems in the book Projectile motion notes Demo: Parabola

Learning Target: I can describe the path of a projectile as a parabola. Vocabulary: parabola

QUESTIONS FOR PROJECTILE MOTION DEMONSTRATION 1.What is the shape that the projectile ball followed? 2.Is the speed of a projectile at the beginning of its journey reallly the same as at the end? 3.How does projectile motion differ from freefall? 4.Is horizontal motion affected by the downward force due to gravity?

END OF CLASS QUESTION 1.What is the acceleration of a projectile just before it hits the ground -9.8 m/s² 1.People in movies ofen jump from buildings into pools. If a person jumps horizontally from 30 meters (the 10 th floor) to a pool 5 m from the building, with what initial speed must he jump? 2.0m/s
