Newton’s First Law states that...

• Every object in a state of motion tends to remain in that state of motion unless an external force is applied to it

• Acceleration is produced when a force acts on a mass

• For every action there is an equal and opposite reaction

Newton’s Second Law states that...

• Every object in a state of motion tends to remain in that state of motion unless an external force is applied to it

• Acceleration is produced when a force acts on a mass

• For every action there is an equal and opposite reaction

Newton’s Third Law states that...

• Every object in a state of motion tends to remain in that state of motion unless an external force is applied to it

• Acceleration is produced when a force acts on a mass

• For every action there is an equal and opposite reaction
