8th - Forces/Motion Test Review

Combination of all forces acting on object

• force

• contact forcef

• field

• net force

Push or pull

• field

• force

• gravity

• drag

Forces on object produce a net force that is 0 N, no motion

• Balanced

• Unbalanced

Forces on object produce a net force that is not 0 N, results in motion

• Balanced

• Unbalanced

Area in which object experiences a force at a distance

• force

• drag

• field

• friction

Force exerted during contact between objects

• distance force

• contact force

• gravitational force

• friction

Force of attraction between objects due to their mass

• gravity

• contact force

• friction

• drag

Contact force between objects that resists the movement of one object

• gravity

• orbit

• field

• friction

Relates gravitational force, mass, and distance

• orbit

• gravity

• law of universal gravitation

• law of who knows what

Force that resists the start of sliding motion between two surfaces touching

• static friction

• kinetic friction
