=Group Lab Design 3 - Eitan, Josh & Solly= = = =TITLE:= = = = = =OBJECTIVE:= To measure the forces exerted by a ball at different angels. = = =PROCEDURE:= We will be using the projectile launcher and a force gauge to measure the force exerted by a projectile at different angels. We will use Silly Putty® to stick a CD case to the sensor, to increase the surface area. We will start by shooting the ball at 15 degree increments, gradually we will narrow the increment we use and eventually we will reach our optimal range of approximately >5 degrees. We will also record distance travelled (displacement) and time of flight.

=HYPOTHESIS:= Josh and I (Solly) believe that the ball will exert more force at a sharper angel because the hight will be greater, allowing gravity to accelerate it more. Eiatan thinks the opposite, he thinks that the ball will will exert more foce at a more horizontal angel.
