Motion and Design Vocabulary List #1
position – the location of an object
speed – a measurement of distance over time
force – a push or pull on an object
energy – the capacity to do work it can be used to move muscles,
operate machines, cook meals and heat rooms
machine – something that replaces human effort
gravity – the force that pulls things toward Earth
balanced forces – forces that have a net force of zero (equal force in
opposite directions)
unbalanced forces – forces that have a net zero force that is not
zero (causes motion)
inertia - the tendency of an object to remain at rest or in motion
unless it is acted on by a force
momentum – the product of the mass and velocity of an object
friction – the force that acts on an object to stop motion
