NON NON – POLY ATTIRE, ID’s AROUND YOUR NECK OBJECTIVE` Be able to solve the x and y components of a vector. Drill 2.10: Drill 2.10: trig functions Date: 11-17-14 Give the equations for sin, cos and tan trig functions. HOMEWORK – due Friday, Nov 21 Nos 56-60 of p 165 REMINDER Next Quiz, Friday!, Nov 21 on Projectile at an angle STAY SEATED, Wait for teacher to say “class dismiss”

2
Projectile Motion Motion In Two Dimensions We restrict ourselves to objects thrown near the Earth’s surface so that gravity can be considered constant.

3
Projectile motion refers to the motion of an object that is thrown, or projected into the air at an angle. The motion of a projectile is determined only by the object’s initial velocity and gravity.

4
Projectile motion applies to sports.

5
Projectile motion applies to destructive projectiles.

6
Projectile motion is a combination of horizontal motion and vertical motion. The horizontal motion of a projectile is constant because no gravitational force acts horizontally

7
The vertical motion of a projectile is nothing more than free fall with a constant downward acceleration due to gravity.

8
The vertical motion of a projected object is independent of its horizontal motion.

10
A projectile moves horizontally with constant velocity while being accelerated vertically. The result is a motion in a curved path.

12
The path of a projectile is called its trajectory. The trajectory of a projectile in free fall is a parabola.

13
A projectile, once projected, continues in motion by its own inertia and is influenced only by the downward force of gravity.

14
An object projected horizontally will reach the ground in the same time as an object dropped vertically. No matter how large the horizontal velocity is, the downward pull of gravity is always the same.

16
Horizontally launched projectile Horizontal velocity is constant. Vertical velocity is changing due to gravitational acceleration.

18
ViVi V ix V iy θ =sinθ V i =cos θ V i

19
ANSWER Nos. 1-6

20
WRAP UP The path of a projectile is a linear curve / round curve / parabolic curve. HOMEWORK – due Friday, Nov. 21 Nos. pp. REMINDER Next Quiz, Friday!, Nov. 21 on Projectile at an angle Stay seated until teacher dismisses the class

21
CLASS DISMISS May the POSITIVE FORCE be with you! 21
