Newton's Law of Motion

1st,2nd,3rd Law

Newton's First Law

Newtons first law states, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force


Example: The ball is staying at rest and will remain at rest until something or someone uses force to move the ball. The ball will also keep rolling if it were to be moved unless something or someone uses force to stop it

Newton's First Law Examples

Newton's Second Law

Force= Mass x Acceleration

If more force is applied than the acceleration increases, if more mass is applied the acceleration decreases

The acceleration of an object is dependent on two variables: net force and acceleration


Example: The dog is using force to pull and accelerate the mass of the rock

Newton's 2nd Law

Newton's Third Law

For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two objects. The size of the forces on the first object equals the size of the force on the second object.


Example: The rider jumps off the skateboard, the jumping is called an action,the skateboard responds to that action by traveling in the opposite direction which is called the reaction.
