Newton’s Third Law of Motion “Law of Action - Reaction”: All forces occur in pairs, and these forces are equal in strength and opposite in direction For every action there is an equal and opposite reactionNewton's Laws of Motion: Everything to do with motion, forces, gravity, speed, or acceleration is governed by these laws.
Newton's First Law (Law of Inertia) An object at rest will stay at rest unless acted on by an unbalanced force An object in motion will stay in motion unless acted on by an unbalanced force
- An object will stay at rest unless acted on by an unbalanced force
- An object in motion will stay in motion unless acted on by an unbalanced force
Inertia – the tendency of an object to resist change in motion (whether at rest or moving)
Mass and Inertia: The amount of inertia an object has depends on its mass
Friction and Gravity: Newton’s First Law of Motion states that an object in motion will stay in motion unless acted on by an outside force Two forces that act on objects are friction and gravity
Friction: acts in a direction opposite to the object’s direction of motion (without friction, the object would continue to move at a constant speed forever) The strength of the force of friction depends on two factors: surface type how hard the surfaces push together
Gravity: the force that pulls objects toward each other
Air Resistance: Objects falling through air experience a type of friction called air resistance As surface area increases, air resistance increases. Eventually, air resistance equals gravity The greatest velocity an object reaches is called terminal velocity In a vacuum, all objects fall at the same rate
Newton’s Second Law of Motion “Force, Mass, and Acceleration”: Force equals mass times acceleration
Newton’s Third Law of Motion “Law of Action - Reaction”: All forces occur in pairs, and these forces are equal in strength and opposite in direction For every action there is an equal and opposite reaction
CONCLUSION:
Newton’s First Law (Inertia): Objects in motion tend to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force
Newton’s Second Law (F=ma): Force equals mass times acceleration (F = ma)
Newton’s Third Law: For every action there is an equal and opposite reaction
