Vocabulary

balanced forces - when the sum of the forces acting on an object are equal the object will remain at rest, or it will move at a constant velocity.

force - a push or pull.

net force - the sum of all of the forces acting on an object.

Newton’s 1st Law of Motion - an object at rest remains at rest unless an external unbalanced force acts on it; an object in motion remains in motion unless an external unbalanced force acts on it.

Newton’s 2nd Law of Motion - an object accelerates in the direction of the net force acting on it.

Newton’s 3rd Law of Motion - for every action, there is an equal yet opposite reaction.

unbalanced forces - when the sum of the forces acting on an object are not equal, the object will accelerate or decelerate.

SP2
Obtain, evaluate, and communicate information about how forces affect the motion of objects.
a
Construct an explanation based on evidence using Newton’s Laws of how forces affect the acceleration of a body. • Explain and predict the motion of a body in absence of a force and when forces are applied using Newton’s 1st Law (principle of inertia). • Calculate the acceleration for an object using Newton’s 2nd Law, including situations where multiple forces act together. • Identify the pair of equal and opposite forces between two interacting bodies and relate their magnitudes and directions using Newton’s 3rd Law.
