Question 1
B2. This question is in two parts. Part 1 is about simple harmonic motion and the superposition of waves. Part 2 is about gravitational fields.
Part 1 Simple harmonic motion and the superposition of waves
An object of mass m is placed on a frictionless surface and attached to a light horizontal spring. The other end of the spring is fixed.
The equilibrium position is at B . The direction B to C is taken to be positive. The object is released from position A and executes simple harmonic motion between positions A and C .
Part 2
Gravitational fields
State Newton's universal law of gravitation.
