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”
Projectile Motion Motion In Two Dimensions We restrict ourselves to objects thrown near the Earth’s surface so that gravity can be considered constant.
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.
The path of a projectile is called its trajectory. The trajectory of a projectile in free fall is a parabola.
A projectile, once projected, continues in motion by its own inertia and is influenced only by the downward force of gravity.
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.
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
CLASS DISMISS May the POSITIVE FORCE be with you! 21
