==Key Stage 3==
===Meaning===
'''Thrust''' is a [[force]] provided sending a [[fluid]] back to propel the [[object]] forward.
===About Thrust===
: '''Thrust''' is a [[force]] so it is [[Measure|measured]] in [[Newton]]s.
: '''Thrust''' is a [[Contact Force|contact force]] because a turbine or propeller must be in contact with the [[fluid]] being used.
: '''Thrust''' can cause a vehicle to [[accelerate]] and can act to counter [[Air Resistance|air resistance]] and [[friction]] to keep a vehicle travelling at a constant [[speed]].
''NB: The [[fluid]] does not need to 'push' against any other material already there. The [[force]] is provided because sending [[mass]] in the opposite direction to the direction you want to go.''
