Newton's 3 Laws of Motion

Newton's 3rd Law

Example: When you are canoeing as you paddle you are exerting force onto the paddle into the water and that effects the boat and cause the boat to move.

Example: When you sit in a chair you are exerting force on the chair and the chair is exerting force on to your body.

Newton's 3rd law is whenever one object exerts force on a second object, the second object exerts an equal and opposite force on the first. (for every action the is an equal and opposite reaction).

Newton's 2nd Law

Example: Person A has a backpack on and Person B does not. Both people start at the same spot and are running. Person B runs faster than Person A because they have less force pushing on them and more acceleration.

Example: If you use the same force to push a truck and push a car, the car will have more acceleration that the truck

Newton's 2nd law is the acceleration of an object depends on the mass of the object and see the amount of force applied

Newton's 1st Law

Example: When you peddle on a bicycle the bicycle moves forward.

Example: When your standing on a bus in the aisle and the bus stops, but your body continues to go forward.

Newton's 1st law is an object at rest remains in rest and an object in in motion remains in motion at a constant speed and in a straight line unless acted by an unbalanced force.
