The formula for calculating force needed to stretch a spring is F = kx, where F is the force in newtons, k is the spring constant in newtons per meter (N/m), and x is the displacement in meters.
The spring constant, represented by k, is a measure of the stiffness of a spring. It is the amount of force required to stretch a spring by one meter.
To convert from centimeters (cm) to meters (m), divide the number of centimeters by 100. In this case, the displacement of 48cm would be converted to 0.48m.
The force needed to stretch a spring is directly proportional to the displacement. This means that as the displacement increases, the force needed to stretch the spring also increases. This is represented by the formula F = kx, where x is the displacement and k is the spring constant.
The formula for calculating force needed to stretch a spring is commonly used in engineering and physics, particularly in designing and testing springs for various applications. It can also be used in everyday situations, such as measuring the force needed to stretch a rubber band or a bungee cord.
