Objectives To examine projectile motion for objects launched at different angles Equipment A computer with internet access Theory To predict where a ball will land when it is shot at some angle above the horizontal, it is helpful to know the initial speed (launch velocity) of the ball. The reverse can also be true and the distance a ball flies, the height a ball reaches, and the time of flight can be used to determine the launch velocity. Activity 1: How does launch velocity affect other projectile parameters? All projectile motion is governed by the kinematic equations given below that you derived in class. x_f=x_o v_x t Equation (X1) v_fy=v_oy a_y t Equation (Y1) y_f=y_o v_oy t (1/2) a_y t^2 Equation (Y2) v_fy^2=v_oy^2 2a_y (y_f-y_o ) Equation (Y3) For this activity, you will use a simple simulation of a soccer kick to examine the relationships between the velocity of the kick, the gravitational acceleration, and the distance traveled by the soccer ball.
