Forces and Speed Flashcards
What is a force?
A push or a pull upon an object.
what force pulls things downwards?
weight
what force acts against anything moving through air?
air resistance
what force acts against anything moving?
friction
what force keeps things afloat?
upthrust
what are forces measured in?
Newtons (N)
what do we use to measure in? Newtons
a Newton meter
what is the difference between gravity and weight?
weight is a consequence of the force of gravity.
what is a balanced force?
forces acting on an object that are the same size but act in opposite directions.
what is a drag force?
it is the force acting on an object moving through air
or water that causes it to slow down.
what is a driving force?
it is the force that is pushing or pulling something.
what is a resistive force?
it is a force that acts to slow down a moving object.
what is a magnetic force?
it is the force between two magnets.
why are forces important?
they are important because they are responsible for changes in motion.
what is an unbalanced force?
Opposing forces on an object that are unequal
