Force and Motion

Equal forces acting on an object in opposite directions

• centripetal force

• inertia

• velocity

• balanced force

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Newton's Second Law

• Inertia

• Acceleration

• Newton's First Law

Force that opposes the motion of objects that move through the air

• friction

• air resistance

• free fall

• gravity

Forces that produce a nonzero net force, which changes an object's motion

• air resistance

• friction

• unbalanced forces

• centripetal force
