Objectives

1. To make sure our cars goes inside the hole by using our own type of launcher.

2. To familiar with projectile analysis and calculation.

Introduction

A projectile is any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown.

(This is an informal definition. The path of a projectile is called its trajectory. A projectile is any

object with an initial non!"ero, hori"ontal velocity whose acceleration is due to gravity alone. An

object ceases to be a projectile once any real effect is made to change its trajectory. The

trajectory of a projectile is thus entirely determined the moment it satisfies the definition of a

projectile. The only relevant #uantities that might vary from projectile to projectile then are

initial velocity and initial position. This project by using racing car (TA$%&A T&' create our

own launcher so that the car goes into the hole 1m away, the launcher system should be based on

mechanical concept such as, spring and rubber. lectric, electronic or chemical concept are not

allowed so by using projectile analysis and calculation we all must calculated how to make sure

our racing car goes into the hole. )alculation of this projectile as shown below.

Mechanism

The launcher for our racing car we use rubber band mechanism. This because of its superior

elasticity. A rubber band, also known as a binder, elastic band, lackey band, laggy band, gum

band, or elastic, is usually ring shaped and commonly used to hold multiple objects together.

This rubber band can generate a lot of forces to push our car because of elastic.

*ased on this mechanism we can say that+

-orces get things going rather than making things stop.

-orces are associated with living things, physical activity and muscular

strength.

%nanimate objects do not apply forces.

-orces keep objects in motion.

hen an object is moving, there is a force in the direction of its motion.

A moving object has a force within it which keeps it going.

-orce is a property of a single object rather than a feature of the interaction

between two objects.

if the pushing force ceases there is a force on the moving object which keeps

it moving but which gradually gets used up and then the object stops.
