Q1(a)

i) The reluctance of a body at rest to move or a moving body to stop is called Inertia.

ii) Three different directions of forces are:

1. Tension: A pulling force that acts away from an object, typically along a rope or cable.
2. Compression: A pushing force that acts towards an object, tending to shorten or crush it.
3. Gravity (Weight): A force that acts vertically downwards on an object due to its mass, towards the center of the Earth.

A neat sketch would typically show:

• An object with an arrow pointing away from it to represent tension.
