What is Newton's 1st law of motion?

• All objects remain at rest or in uniform motion along a straight line unless acted by an external force.

• The greater the force, the greater the acceleration.

• Every action has an equal and opposite reaction.

the result of unbalanced forces.

Key observations regarding an object’s motion :

1) development of the concept of velocity using inclined planes

2) development of the idea of force that causes the motion of an object

3) being at rest is the natural state of an object

4) inertia is the resistance of an object to changes in its motion

• Galileo's Law of Motion

• Newton's Law of motion

• Aristotle

• Empedocles
