A particle is in linear simple harmonic motion between two points, A and B, 10 cm apart. Take the direction from A to B as the positive direction and give the signs of velocity, acceleration and force on the particle when it is at the mid-point of AB going towards A.

Discuss with your friends and give examples of subsets of sets from your daily situation.

Give one example in each case that happens around you: Slow and fast change.
