Spring constant, K =1586 N/m,
Mass of the object, m=0.028kg
Height between the object and ground in y-axis, H= 1.29m,
Angle, θ = 00
Assume constant downward acceleration, g = 9.81ms-2
Initial Velocity, VO = s (g/2x)-1/2
Kinetic Energy, KE = (1/2) mv2
Elastic Potential Energy, EPE = (1/2) kx2
Table1.2: Table consists of Length of spring being compressed, Horizontal range of ball bearing fly, Initial Velocity, Kinetic Energy, and Elastic Potential Energy.
Graph 1.2:
Graph of Kinetic Energy, KE against Elastic Potential Energy, EPE
From the graph 1.2, found that the gradient = 0.7076.
(1-0.7076)/1 x 100% = 29.24%
Therefore, the error of percentage = 29.24%
