Useful Definitions for Newton’s Laws
Newton’s 1st Law – An object at rest will stay at rest and an object in motion will continue moving, in the same direction and with the same velocity, unless _______________ on by a/an _________________ force.
Inertia – The property of an object that __________ changes in its motion.
Objects with more __________ have more inertia and therefore more _________________________ to changes in their motion.
The greater an object’s inertia, the ____________________ the force needed to change its motion.
_________ Force – The result of adding up all the forces that are acting on an object.
A balanced net force will result in no change in __________.
An unbalanced net force will result in a change in _______________ or _________________.
Newton’s 2nd Law – the acceleration of an object is directly proportional to the _____________ acting on it and inversely proportional to its ________.
The stronger the net force the greater the _____________________.
A larger mass will create a smaller net force and therefore less ______________________.
Newton’s 3rd Law – For every action force there is a reaction force equal in __________________ and ____________________ in direction. Anytime a force is ____________ to an object you get the 3rd Law in action.
Forces ___________ in pairs when pushing, pulling, colliding…etc.
The pushing, pulling, colliding can be applied by both objects or by only one of the objects and you get the ______________ result.
The object with less mass will have the ____________ acceleration (a= F/m).

Useful Definitions for Newton’s 1st Law
Newton’s 1st Law – An object at rest will stay at rest and an object in motion will continue moving, in the same direction and with the same velocity, unless acted on by an unbalanced force.
Inertia – The property of an object that resists changes in its motion.
Objects with more mass have more inertia and therefore more resistance to changes in their motion.
The greater an object’s inertia, the greater the force needed to change its motion.
Net Force – The result of adding up all the forces that are acting on an object.
A balanced net force will result in no change in motion.
An unbalanced net force will result in a change in velocity or direction.
Useful Definitions for Newton’s 2nd Law
Newton’s 2nd Law – the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass.
The stronger the net force the greater the acceleration.
A larger mass will create a smaller net force and therefore less acceleration.
Useful Definitions for Newton’s 3rd Law
Newton’s 3rd Law – For every action force there is a reaction force equal in strength and opposite in direction. Anytime a force is applied to an object you get the 3rd Law in action.
Forces work in pairs when pushing, pulling, colliding…etc.
The pushing, pulling, colliding can be applied by both objects or by only one of the objects and you get the same result.
The object with less mass will have the greatest acceleration (a= F/m).
