When the string is pulled at an angle, the vertical component of the pulling force (( F \sin \theta )) reduces the normal force (( R )) of the block on the surface. Since friction (( f )) is proportional to normal force (( f = \mu R )), friction decreases as angle increases. To maintain constant velocity (if required), the spring balance reading may actually change. However, if the question asks purely about theoretical work , we ignore friction.
Lukiskan sebuah pada graf untuk menandakan titik pilihan anda (saiz segi tiga hendaklah sekurang-kurangnya pada kertas graf).
) to stretch the spring or the stored. Formula : Example Calculation : If the force at an extension of ), the work done is: Practical Tips for Students Units : Always convert extension from centimeters ( ) to meters ( ) before calculating work in Joules ( When the string is pulled at an angle,
Efficiency is a measure of how much of the input energy is converted into useful work. It is calculated using the equation:
m=x2−x1F2−F1m equals the fraction with numerator x sub 2 minus x sub 1 and denominator cap F sub 2 minus cap F sub 1 end-fraction : Menggunakan titik However, if the question asks purely about theoretical
