Newton's First Law

• an object keeps moving or stays still unless and unbalanced force acts on it

• F= m x a

• for every force, there is an equal and opposite force

• don't push or pull

Newton's Second Law

• an object keeps moving or stays still unless and unbalanced force acts on it

• F= m x a

• for every force, there is an equal and opposite force

• don't push or pull

Newton's Thrid Law

• an object keeps moving or stays still unless and unbalanced force acts on it

• F= m x a

• for every force, there is an equal and opposite force

• don't push or pull

The greater the mass,

• the greater the inertia

• the less the inertia

• the less the force required to move it

• the greater the velocity
