UPDATED COMPLETE QUESTIONS AND
VERIFIED SOLUTIONS

●● scalars
Answer: forces with magnitude but no direction


●● contact forces
Answer: requires contact eg friction


●● non contact forces
Answer: doesnt require contact eg gravity


●● mass and weigth
Answer: directly proportional


●● weight
Answer: mass x gravitational field strength


●● gravitational field strength on earth
Answer: 9.81

,●● resultant force
Answer: the overal force acting on an object


●● if a resultant force moves and object
Answer: work is done


●● scale drawings
Answer: triangular drawings, finding the hypotenuse usually using
pythagoras or trigonometry


●● object in equilibrium
Answer: when to forces acting on the object are balanced


●● extension
Answer: directly proportional to force


●● (spring) force
Answer: spring constant x extension


●● limit of proportionality/elasticity
Answer: when an elastic object gets stretched too much and it become
plastic

, ●● moment of a force
Answer: force x perpendicular distance from pivot to the line of action
of the force


●● levers
Answer: make it easier to do work and increase the distance form a pivot


●● gears
Answer: transmit rotational effects


●● pressure of an obeject
Answer: force ÷ area


●● pressure in fluids
Answer: height above point X density of fluid X gravitational field
strength


●● pressure of a fluid
Answer: a force is exerted at right angles to any surface in contact with
the fluid


●● a floating object
