| What is Weight, weightlessness & where does the weight of an object act on? | 1) Weight - Force acting on an object due to gravity (non-contact) 2) Weightlessness - astronauts seem to be weightless because both they and the space station are constantly falling towards the Earth (as they are still in earth's gravitational field) 3) Centre of Mass - the weight of an object acts at its centre of mass |
| What are Resolving Forces, how can they be shown? | - (Opposite of Resultant Forces) A single force can be resolved (broken down) into two component forces at right angles to each other - Can be shown on Vector Diagram |
