Physical Science Ch.12

Force

• It's a push or pull on an objects.

• A field force that acts between any two objects.

• Is a contact force that works against the motion of objects moving past each other.

• studies the forces and how they can change an object's motion.

Dynamics

• Act between objects that are not touching.

• studies the forces and how they can change an object's motion.

• The acceleration of an object is directly proportional to the net force acting on the object and is inversely proportional to its mass.

• act only when one object touches another.

Newton's 1st Law

• The acceleration of an object is directly proportional to the net force acting on the object and is inversely proportional to its mass.

• act only when one object touches another.

• Objects at rest remain at rest, and objects in motion continue in a straight line at a constant velocity unless

• Act between objects that are not touching.

Newton's 2nd Law

• A field force that acts between any two objects.

• Objects at rest remain at rest, and objects in motion continue in a straight line at a constant velocity unless

• The acceleration of an object is directly proportional to the net force acting on the object and is inversely proportional to its mass.

• shows the object and that forces acting on it's vectors.

Newton's 3rd Law

• The acceleration of an object is directly proportional to the net force acting on the object and is inversely proportional to its mass.

• A force that accelerates an object toward the center of a circular motion.

• shows the object and that forces acting on it's vectors.

• For every action force, there is an equal and opposite reaction force..
