7th Grade Science: Unit 04 Flashcards

Front

equal and opposite forces on an object that result in no change in position, direction, or motion; combined net force equals zero

Back

balanced forces

Front

Term for 'the combination of all forces acting on an object'.

Back

net force

Front

an object will remain in its current state of motion or at rest unless an outside net force acts on it

Back

newton’s first law of motion

Front

What is the term for the following definition: 'unequal forces acting on an object that may result in a change in position, direction, or motion; combined net force does not equal zero (greater than zero)'?

Back

unbalanced forces

Front

the rate at which an object changes its velocity

Back

acceleration

Front

Term for: 'a push or pull on an object; forces have both strength and direction'

Back

force

Front

Term for 'a force that acts in the opposite direction to movement'.

Back

friction

Front

the force that pulls objects toward each other

Back

gravity

Front

the mass of an object in motion

Back

momentum

Front

the SI (international system) unit of force; it measures how much force is needed to accelerate a 1-kilogram mass by 1 meter per second squared

Back

newtons
