Force and Motion

A system of objects that are not moving with respect to one another.

• Velocity

• Acceleration

• Frame of Reference

• Momentum

the speed and direction of a moving object

• inertia

• velocity

• momentum

• acceleration

NGSS.MS-PS2-5

A force that opposes motion between two surfaces that are in contact

• air resistance

• unbalanced forces

• friction

• inertia

The force that is equal in strength and opposite in direction to the action force, which acts simultaneously on whatever is exerting the action force.

• reaction force

• action force

• net force

• air resistance
